The end is near for 'Prison Break'

The wild ride is almost over for the good, the bad and the ugly on "Prison Break."

For the last season there will be several twists and turns, surprises, returning characters and a death or two along the way.

Fans want to know what will happen to brothers Michael Scofield (Wentworth Miller) and Lincoln Burrows (Dominic Purcell), who have survived some incredible, and maybe also improbable, adventures.

After a riveting first season in which the ever-cool mastermind Michael helped the wrongly convicted Lincoln escape from the Fox River Penitentiary, they have been on the run.

Michael landed in a Panama prison, and, after another breakout, he and Lincoln are trying to bring down a mysterious conspiratorial agency called "The Company".

"Prison Break" often stretched the bounds of credibility. Part of the fun was in seeing how thin the stretch would be. Producer Olmstead says the biggest stretch for him was when Michael's body tattoos were erased overnight. Michael first went to jail with the floor plans of the prison worked into a full-body tattoo. By the second season, actor Miller was suffering from skin irritations from the temporary tattoos.

To explain the removal of the tattoos, "we kind of fudged it a little bit when he went to a supersecret tattoo removal place," Olmstead says.

A bigger stretch according to some, involved the show's resident villain Theodore "T-Bag" Bagwell (Robert Knepper), who while on the run had a hand chopped off by an ax.

The evil T-Bag then forced a veterinarian to sew it back on. Amazingly, he survives the ordeal only to cut the hand off himself later in the story (to escape after being chained to a radiator).

He eventually got a prosthetic hand, presumably from a poor guy that had the misfortune to cross paths with T-bag in a bar. But how he attached it remains a mystery.

Olmstead says T-Bag is "a real cockroach" who is able to survive to cause trouble. "But obviously he's a big fan favorite," he says. "And it's a bit heartbreaking to see where he ends up. But it makes perfect sense."

Olmstead also says there's a "big surprise reveal" on the way with a returning character that will really shake things up. He says the relationship between Michael and Sara (Sarah Wayne Callies) "wraps up unexpectedly. It's bittersweet but very satisfying.".
