Prison Break fans, listen here: Robert Knepper will reprise Theodore “T-Bag” Bagwell, the slimy, handicapped villain from Prison Break, on tonight’s episode of Breakout Kings. In an interview with TVLine, Knepper shared his excitement about bring back the fan favorite everyone loved to loathe.

“Nick Santora – one of my favorite writers on Prison Break – wrote me an email right before we started shooting, saying, “You know what? I think this might be the best dialogue I’ve ever written for T-Bag.” And I’m here to tell you it was. It was all the familiar things you love to hate about T-Bag – the danger, the humor – but it was interesting to highlight him in this episode by saying, “Let’s try to get in his head a bit. Let’s figure out why he’s doing this.” And the pathos and emotion that comes out is just…. I could not have just jumped into this thing if I hadn’t had four years of basically getting ready for it.”

When asked why is escapes prison this time around he said, “There is a huge reason. I’m not going to give it away, because it’s so beautiful, and it’s such an incredibly important reason. I will tell you that he’s not escaping to escape. It’s not just, “I want to be free.” He has a very, very specific reason for doing it, and it will break your heart.”

Knepper’s four-episode guest stint on Breakout Kings begins tonight in “The Bag Man” at 10PM on A&E. Check out a handful of images in the gallery below.
