Inside Sona, Michael is telling Mahone that they've got to replace everything they lost -- starting with a new exit point. But before the two can talk further, Mahone is distracted by Tyge walking by. Both of them watch him walk up to Whistler and say, "I know you." Whistler tries to blow him off, but Tyge presses, "You're McFadden, right? Nice, 1997?" Whistler is all, "You've confused me with someone else," but Tyge persists, "No, no, no, I swear. You were with the ambassador." Both Mahone and Michael are openly watching this. Whistler says coldly, "You've mistaken me for someone else." Tyge gives him a skeptical look and walks off without another word.
Whistler comes over to Michael and Mahone, both of whom are giving him looks like, McFadden, eh?. He protests that Tyge is merely silly from the heat. Mahone finally breaks the awkward silence with, "C'mon, guys, I got something to show you."
He walks them over to the window where he spent the better part of an afternoon drooling in an opium haze, and after a moment, they all watch a day-shift guard walk across the courtyard and toss his empty coffee cup on the ground. It rests right next to a previously-discarded cup. Mahone points out of the guard, "He has one in the morning and one at lunch...a man's gotta have his fix. If we get to that cup..." "We get to the man," Wheeler concludes. Michael urges, "We've got to move." And move they do -- right toward the end credits.
