Frypan

The Fever Code

Siggy makes one appearance in The Fever Code. After George is stung by a Griever, Siggy tells the other Gladers about a syringe of liquid that had come up in a box of supplies. Since he had no idea what it was for, he had not mentioned it to anyone. Alby tells him to bring the syringe, and they inject George with it.

The Maze Runner

In The Maze Runner, Siggy is first mentioned by Gally and Chuck to be a little ill-tempered. However, he actually seems to be friendly enough. Siggy later grows to be a good friend of Thomas and speaks up for him during a Gathering, along with Newt, Minho, and Clint. He is the Keeper of the Cooks in the Glade, or maybe the only one. The other Gladers joke about the food he prepares being horrible stuff, but the truth is that Frypan is a very good cook and they enjoy their meals. It is said that Siggy is the last Keeper to agree to follow Thomas into battle. He escapes with the other 19 survivors.

The Scorch Trials

In The Scorch Trials, Siggy appears a few times, talking occasionally to Thomas, Newt, Minho, Winston, and Jack. He is only made notable when helping Winston leave the Flat Trans. He is also the one who spots Thomas and Brenda in the Crank City when they are trapped in a dead end. Siggy witnesses them being threatened and forced into a basement party by three Cranks (Blondie, Tall and Ugly, Ponytail) and together with the other Gladers and Jorge, rescues Thomas and Brenda.

The Death Cure

In The Death Cure, Siggy originally chose not to get his memory restored, but a short time later, he changed his mind. Siggy is not seen afterwards until he and the other Immunes meet up with Thomas in the Maze. He then runs with all of the others and escapes into the Flat Trans.

The Maze Runner

In the Maze Runner film, Frypan witnesses Thomas being brought up into the Glade via the Box. He scans Thomas and chortles that he does need help in the kitchens before the latter tries to make a break for it, only to trip and fall. When Gally stops Thomas from walking into the Maze, Frypan and the Gladers join Gally in stopping Thomas from walking into the Maze. Later, Frypan watches as Thomas wrestles with Gally and is one of the first members to congratulate him. He hands Thomas a Mason jar of Gally's brew and tells him "Welcome home, Thomas," before a Griever roars in the distance behind the Maze walls. After Thomas and Minho survive the Maze for a night, Frypan voices his concerns about Minho making Thomas a Runner right away, saying, "Let's not jump to conclusions." He observes Teresa coming up in the Box and backs away when she comes to, sputtering for air before saying Thomas' name and falling unconscious again. When Thomas insists on returning to the Maze to look at the Griever corpse, Minho invites Frypan to join them. He helps pull the Griever leg apart from the squished body and Minho retrieves a metal cylinder with a digital screen reading, "07." He is present when the group presents their findings to Newt and Gally back at the Gathering hut. Gally argues with Newt over how to handle Thomas and the fact that he continues to break the rules of the Glade and Newt overrules him, saying that Thomas can become a Runner after staying one night in the Pit without food. Angered, Gally storms off and Frypan tries to stop him, only to be rebuffed by the other Keeper. Frypan joins the other Gladers as they hide and try to avoid the Grievers when the doors stop closing. He and the other Keepers are forced to restrain an angry Gally, who punches Thomas in the face and blames him for all of the problems that happened since he came up in the Box. Thomas stabs himself with the Griever's stinger and Frypan rushes to help as Thomas starts to lose consciousness. Days later, Gally takes command and decides to use Thomas and Teresa as bait for the Grievers to take for the next night. Eventually, Thomas, Teresa, Newt, Minho, and Frypan fight back, revealing that they intend to leave the Glade to find life outside the Maze. He and the small group of Gladers planning to leave fight off the Grievers as they make their way to the concealed entrance in Section 7. Once the code has been input, the Gladers find themselves in a dimly lit hallway, Frypan noting a clearly marked door with an Exit sign. The group steps around the bodies of the WCKD techs that were shot and killed as they enter the control room where the techs were watching them. Frypan watches the message left by Ava Paige explaining why the Maze trials were done. He starts to leave the lab with the others until they hear Gally, who has been stung by a Griever. Gally tells them that they can't leave before shooting at Thomas, only for Chuck to take the bullet instead, while Minho throws a spear into Gally's chest. Frypan hangs his head as Chuck dies in Thomas' arms before soldiers invade the base and grab the survivors, claiming that they are taking them somewhere safe.

The Scorch Trials

In the Scorch Trials film, Frypan escapes WCKD along with the others. He travels through the Scorch and makes it to the Right Arm, fighting with his friends when WCKD attacks the group and captures Minho, Aris, and Sonya. He is among those who remain free, together with Thomas, Newt, Brenda, Jorge, Harriet, and Vince.

The Death Cure

In the Death Cure film, Frypan helps Thomas, Newt, Brenda, Jorge, Harriet, Vince, and the Right Arm rescue Aris, Sonya, and a group of Immunes and take them to their new hideout.

When Thomas leaves the hideout to go to the Last City to rescue Minho, Frypan and Newt join him. They drive into the sewers, where the Cranks attack them, Frypan shoots at them with a shotgun, but soon runs out of ammo. Brenda and Jorge arrive and save them from the Cranks. Thomas tells Brenda that he didn't want to put anyone in danger and Frypan thanks Brenda and Jorge for saving them.

Frypan, Thomas, Newt, Brenda, and Jorge arrive in the Last City. Thomas is scanned at the gate, and the WCKD guards recognize him. Frypan, Thomas, Newt, Brenda, and Jorge run from the turrets and into a safe corner where a group of masked men rescue them and take them to a hideout, where one of them reveals himself to be Gally, Frypan, Thomas, Newt, Brenda, and Jorge are shocked to see him. When Thomas punches Gally in the face for killing Chuck, Newt stops Thomas and calms him down. When Jorge asks Frypan if he knows Gally, Frypan tells him that Gally was an old friend.

Gally introduces them to Lawrence, who lets Thomas, Newt, and Gally go into the Last City while Frypan, Brenda, and Jorge stay behind.

Later, in the building, Frypan, Thomas, Newt, Gally, Brenda, and Jorge go over plans to use Teresa to get into WCKD. Thomas is reluctant to use Teresa to get into WCKD, Newt reacts with extreme aggressiveness, screaming at Thomas for still having feelings for Teresa. After this, Newt calms down and apologizes. Later, Newt reveals to Thomas that he has been infected by the Flare.

Thomas gets Teresa to follow him into an alley where Gally captures her. Thomas and Gally take Teresa to an abandoned church where Frypan, Newt, Brenda, and Jorge are. Frypan watches Gally question Teresa before Thomas convinces her to remove the trackers from their necks. Frypan climbs up a crane while Thomas, Teresa, Newt, and Gally go into the WCKD headquarters, Brenda goes to a parking lot to steal a bus, and Jorge returns to the Right Arm's hideout.

Gally rescues the Immune children and takes them and a serum that he had retrieved from a safe to Brenda. While Gally goes back to the WCKD headquarters to find Thomas, Newt, and Minho, Brenda drives the Immune children out of the garage, but is cornered by WCKD soldiers. Brenda fires a flare gun into the sky to signal for Frypan to save them with the crane.

Frypan, Brenda, and the Immune children discover that Lawrence has gone to destroy the wall to the Last City, Jorge and Vince arrive with a berg to rescue them. They fly into the city to get Thomas, Newt, Minho, and Gally.

Frypan, Brenda, Jorge, Vince, and the Immune children are waiting at the berg when they hear Teresa telling Thomas that his blood can cure Newt like it did Brenda, Minho and Gally arrive, asking where the serum is. Frypan, Minho, Gally, and Brenda arrive to see that Thomas has killed Newt. Frypan, Minho, Gally, and Brenda gather around Newt while Thomas walks off back to WCKD.

Frypan, Minho, Gally, and Brenda return to the berg where Jorge flies them, Vince, and the Immune children to the top of the WCKD building where Thomas and Teresa are. Thomas is too wounded and weak to get on the berg due to being shot in the stomach by Janson, but with Teresa's help, they and Vince manage to haul him on board. Teresa falls to her death when the WCKD building collapses.

Frypan, Thomas, Minho, Gally, Brenda, Jorge, Vince, and the Immune children fly to the Safe Haven to live in peace.
