Theodore
The Arconia's most pampered—and unimpressed—resident.

Lore & Background
Theodore is the pampered pooch of Uma Helmsley, the Arconia's resident grump and board member. He is frequently seen being walked or carried by Uma, often dressed in a stylish coat or harness. While Theodore has no lines or major plot involvement, his presence adds to the quirky atmosphere of the building. He is notably unbothered by the chaotic murder investigations happening around him, maintaining a stoic and slightly judgmental demeanor that perfectly matches his owner's personality. Fans have speculated that Theodore may be the only truly innocent resident of the Arconia.
In Their Own Story
In Season 1, T-Bag attempted to ensnare Michael Scofield as a sex slave but failed. During a race riot in "Allen", his cellmate was fatally wounded; believing Scofield responsible, he sought revenge until stopped by John Abruzzi. Returning in "Riots, Drills and the Devil", he instigated a full-scale riot, accidentally learning of the escape attempt and blackmailing the group to include him. He murdered a guard to prevent exposure and framed his friend Trokey. After being given an ultimatum by Abruzzi in "Odd Man Out"—back out or die—he slashed Abruzzi's throat with a razor blade. In the final episode, he escaped Fox River but was handcuffed to Michael. Abruzzi cut off Bagwell's cuffed hand with an axe, leaving him for dead. T-Bag survived, staggering through the woods with his severed hand tucked in his armpit.
Reader's Guide
In Season 2, a veterinary surgeon named Dr. Marvin Gudat reattached T-Bag's hand before being murdered by Bagwell. He bleached his hair and traveled to Utah for four episodes to find Charles Westmoreland's hidden money. After stealing the five million dollars from fellow fugitives in episodes five through seven, he separated from the main plot. Captured by Brad Bellick and Roy Geary at Hollander's house, he hid a locker key in his sock. During torture, after swallowing the key, he passed it while tied to a toilet with laxatives. In "Bolshoi Booze", he re-severed his hand to escape plastic cuffs. He tracked down and killed Geary by smashing his head with a champagne bottle, framing Bellick for the murder using a credit card receipt. In the fall finale "The Killing Box", it is implied he killed a Vietnam war vet to take his prosthetic hand.
