1	1	"Splinter"	Jeffrey Reiner	Terry Matalas & Travis Fickett	January 16, 2015 (2015-01-16)	1.353
In 2043, scientists led by Katarina Jones complete a Project Splinter time machine to stop an apocalyptic plague before it happens. Their best lead is a corrupted 2017 recording from virologist Cassandra "Cassie" Railly which identifies Leland Frost with the plague's origins and prophetically asks for James Cole, whom Jones recruits as a chrononaut. Cole questions Cassie in 2013, proving he is a time traveller by causing a scratch to appear on a future version of her watch, but she does not yet know about Frost. Cassie investigates on her own, and, when they meet again in 2015, she has identified Frost as Markridge Group CEO Leland Goines who is working on biological weapons. Cole fails to assassinate Goines, and they are captured. Goines realizes that Cole is a time traveller he met in 1987 when Cole was looking for the Army of the 12 Monkeys. Knowing he will survive to do this, Cole puts the two versions of Cassie's watch together, creating an explosive paradox. He kills Goines but it does not rewrite the post-apocalyptic future. Elsewhere, psychiatric patient Jennifer Goines inherits her father's fortunes and is shown drawing the monkey logo.
2	2	"Mentally Divergent"	David Grossman	Natalie Chaidez	January 23, 2015 (2015-01-23)	1.104
Cole is directed to find information about a patient in a Philadelphia mental institution who is somehow linked to the "Army of the 12 Monkeys". The scientists attempt to send him to 2015, but he finds himself in North Korea in 2006. An interrogator finds his note with the institution's address. After being redirected to 2015, Cole finds the mentally unstable Jennifer Goines in the institution. Cassie gets Aaron Marker to take her to her parents' old bookstore to hide and tells him there is a cover-up about Leland Goines's death. Aaron tells her of intelligence that Cole was in North Korea in 2006 and gives her the address from Cole's note. At the institution Jennifer tells Cole that she worked for her father and is one of only two people left who know the location of his secret laboratory, the Night Room. Just as Cassie arrives at the institution to get Cole, a mysterious pallid man with a scar arrives and kidnaps Jennifer. He is revealed to be the man who killed Jennifer's two coworkers at her father's lab (leading to her mental breakdown) and Cassie's ex-NSA contact Jeremy.
3	3	"Cassandra Complex"	Michael Waxman	Rebecca Kirsch	January 30, 2015 (2015-01-30)	0.903
Cole and Cassie attempt to track down Henri Toussaint, the only person besides Jennifer to know where the Night Room is. They discover he was murdered by an unknown assailant while working with Cassie to contain an epidemic in Haiti in 2014. Cole is sent back to 2014 Haiti, where he locates Henri, but the Pallid Man catches up to them. The 2014 Cassie—paranoid that the Haitian outbreak is the 2017 plague—has a breakdown and is relieved of duty. Cole helps Henri escape the Pallid Man, and Henri tells him how to find the Night Room. The Haitian epidemic turns out not to be the plague, and Cole rejoins Cassie in 2015. Cassie takes a job at the CDC to gather further information on the Night Room. It is revealed (though not to Cassie) that Cole murdered Henri to stop the Army from interrogating him. In 2043, Ramse encounters Max, a woman he knew from when he and Cole were members of a group called the West VII. He is suspicious of her claim that she has left the West VII but lets her go. She reports to Deacon, leader of the West VII, that she has found Cole.

In 2043, the West VII assault the temporal facility where the time machine is housed, entering through a hidden tunnel. Ramse and Jones are apparently killed but not before Jones sends Cole back to 2015. Flashbacks reveal how Cole and Ramse joined the West VII and how Cole and Max became intimately involved. Some time later, Ramse challenges Deacon's brutality, and Deacon asks Cole to kill him. At the last minute, Cole refuses and flees the West VII with Ramse, leaving Max behind. In 2043, the time machine malfunctions and sends Cole back just a few days. He is captured by Deacon and forced to reveal the location of the hidden tunnel (his going back in time made the attack possible in the first place). Max frees Cole and they use his foreknowledge of how the attack happened to defeat Deacon's soldiers, saving Ramse and Jones. Deacon sees the time machine and escapes and Max joins Project Splinter. Cole then returns to 2015, where Cassie has discovered the location of the Night Room.

Cole and Cassie break into the Night Room, finding the Army of the 12 Monkeys had got there first after being told where it is by Jennifer. The Pallid Man tortures Cole for information on how to break into the Night Room's vault, revealing to Cassie that Cole had killed Henri. Later, Cole explains to Cassie why he killed Henri and reveals more of his past to her. In 2043, Ramse discovers that Jones had sent other chrononauts into the past before Cole, some of whom had died. He confronts Jones but grudgingly agrees to go along with her after she promises to protect Cole. In 2015, the Army manages to cut open the vault door, revealing the source of the plague virus, a centuries-old preserved human torso. The Pallid Man tricks Jennifer into deactivating the vault's final failsafe, but Cole and Cassie incinerate the viral specimen. Cassie is captured by the Army and Cole splinters away, finding himself in an alternative 2043 where the West VII have taken over the temporal facility.

Cole learns that in alternative 2043, Cassie was killed in 2015, causing drastic changes to the timeline, the plague emerged earlier and was linked to an event called Operation Troy. Cole convinces the leader of the West VII—who, in this timeline, is Ramse—to let Jones send him back in time so he can prevent Cassie's death. After being shot in an argument, the dying Jones sends Cole back to 2015, telling him to ask his version of Jones about "sacrifice". In 2015, Cole kidnaps Aaron Marker and forces him to help him rescue Cassie. The Pallid Man drugs Cassie with a hallucinogen and an unnamed female member of the Army guides her through the hallucinations, saying that she is taking Cassie to meet "the Witness". Cole and Aaron track down and free Cassie, and Cole splinters in front of Aaron. Aaron apologizes to Cassie for not believing her, and they resolve to investigate Operation Troy.

Cassie and Marker investigate Operation Troy and the artefact fragments Cole found, deducing that Markridge Group's M5-10 is being used to kill CIA-leaker Adam Wexler in Chechnya. Cole splinters away and hours later calls Cassie from Chechnya, explaining that information she and Marker will give him one week in the future allowed him to take possession of the virus before the Army of the 12 Monkeys. Mercenaries capture Cole and Wexler opens the case, exposing them all to the virus. As the mercenaries begin dying, they offer to trade Wexler for medical aid and Cole convinces Wexler to open fire on the mercenaries. Before dying, Wexler tells Cole that the Army of the 12 Monkeys were involved in a 1987 yakuza war in Tokyo. Cole calls Cassie, allowing the CIA to trace his location to burn the virus with Predator drones and begs her not to tell him of his fate when they meet in a week. Marker threatens the CIA with exposure to gain his and Cassie's release, and Cassie follows through with Cole's wishes to not let him know he is going to his death.

In 2043, Jones sends Ramse and Whitley to Spearhead, a military colony, to ask for help stabilizing the time machine's energy core. It is revealed that Jones and Whitley once lived at Spearhead but left after its leader, Colonel Foster, took power in a bloody coup. Foster declines Jones's request, saying he needs the resources to work on a cure for the plague. Ramse encounters Elena, an old flame and discovers he is the father of her son, Sam. When a failed attempt to retrieve Cole destroys the energy core, Jones comes to Spearhead to request the use of their core. Foster eventually agrees on the condition that Jones return to Spearhead to work on the cure. Ramse suggests accepting Foster's offer, but Jones remains convinced that the virus is incurable and resolves to obtain Spearhead's energy core by any means necessary. In 2015, Cassie travels to the site of the airstrike to determine if Cole is truly gone. She concludes that he has been erased from the timeline and the plague has been averted. It is revealed that Cole is alive but stranded in 2017 where the plague is well underway.
9	9	"Tomorrow"	TJ Scott	Rebecca Kirsch	March 13, 2015 (2015-03-13)	0.708
In 2043, Jones orders her team to seize Spearhead's energy core. She kills Foster, her group captures the core and reenergizes the time machine at the cost of many lives, including Whitley's father. Ramse takes Sam and Elena to safety; the latter claims Foster had a cure for the virus and suggests Jones is lying. Jones is seen destroying a page from Foster's research showing that the 2040 virus was cured. Flashbacks to 2041 reveal how Cole and Ramse met Jones and how Ramse coerced Cole into joining Project Splinter. In 2017, Cole is brought to the CDC to see a dying Cassie. She tells him that a lot happened between them after 2015 and gives him an important address before dying. Jennifer appears, preaching to a group of refugees about "daughters" and an "army". As Cole splinters away, the scratch he made on Cassie's watch in 2013 disappears. Back in 2043, he argues with Ramse, who says Jones lied about Foster's cure and wants to end Project Splinter to ensure his family is not erased from the timeline. Cole retorts that the project is the only way to stop the virus and save Cassie, and the two come to blows.

Cole appears in 2015, shocking Cassie and Aaron. He and Cassie find the journal of Dr. Oliver Peters, the plague's creator, which points them to Tokyo in 1987. After Cole returns to 2043, Cassie tracks down Peters, who was forced to recreate the virus by the Army. He begs Cassie to kill him, but she lets him go. The unnamed female member of the Army meets Aaron and asks him what he would do to protect Cassie. In 2043, Ramse destroys Jones's research on the history of the plague and steals the drug that allows Cole to splinter. Fleeing, he encounters the Daughters, an all-female sect led by an aged Jennifer. She tells him about the Witness and says Ramse will be a friend to them. In pursuit of Ramse, Jones's men kill Elena. Ramse returns to the temporal facility and tries to blow up the time machine, failing but killing Max. Trapped, he injects himself with the time-travel drug and splinters to 1987 Tokyo. Before sending Cole after Ramse, Jones warns him he must complete the mission this time as his body can only take one more jump before failing; Cole vows to kill his friend should the latter interfere.

During his imprisonment for the stabbing, Ramse is contacted by Olivia, the mysterious member of the Army of the 12 Monkeys. Upon his release in 1995, he is initiated into the Army. Flashbacks cover events from the 1990s to 2015, revealing that the Army invested in Markridge's development of the plague virus and that Ramse, believing he killed Cole in 1987, used his knowledge of Cole's actions to help the Army foil all of Cole's attempts to stop the plague and ensure that all events happened as he remembers them from 2043. In 2015, Aaron loses his job and becomes involved with the project that will become Spearhead. He sees that Olivia will direct that project. Jennifer is found by the Army and taken in by Olivia. In 2043, a desperate Jones sends the injured Cole from 1987 to 2015, stranding him in that time. Jones's subordinates abandon her, believing Project Splinter is over.

Aaron gives the Army Cole's location in exchange for ensuring Cassie's safety. When the Army comes for Cole, Cole's father dies defending him. Cole injects himself with the blood sample, causing an explosive temporal paradox that cures him and drives off the Army. Cole, Cassie and Jones leave the young Cole in foster care, and Jones tells Cole that the cure has removed his ability to travel through time.

It is revealed that Ramse is not the Witness, and Cassie and Ramse are shot. Cole uses the machine to send Cassie to 2043, in the hope that Jones will be able to save her and helps the less-gravely wounded Ramse escape.

With help from the Jennifer of 2020, they break the loop and return to 2044. They explain to Jones that her creation of Project Splinter was fated and attempting to alter that fate caused the loop. To escape it, they saved Hannah and gave her to Jennifer's Daughters to raise, letting Jones believe she was dead so that she would start the project. They then reunite Jones with the adult Hannah. Cole tells Cassie about his feelings for her, but she rebuffs him, fearing that they stand to lose too much if she reciprocates.
