Prison Break - Mahone’s Ghosts

Mahone is seeing Haywire because the “ghosts” of what he has done have always haunted Mahone (remember Shales caused him to start taking the drugs) but Haywire was the most “paranoid” of all the people he killed (remember how Haywire acted around Michael - “It’s a maze, it’s a maze”, the guy was a nut) — so when Mahone started going through real bad withdrawal and started becoming paranoid himself, the most paranoid ghost of those he killed came back to haunt him, though he haunted him through his mind. Haywire’s personality best personified how Mahone was feeling through most of Good Fences.
