what led me to that conclusion was the shot on the previews of a man with french cuffs, expensive watch, and braces sitting down ....dressed and moved like Patrelli. That got me thinking about it enough to rationalize that (a) he's clearly got a lot to hide in his past, (b) we've already seen that he's not above screwing around on his wife, wheelchair or not, and (c) i doubted they would introduce a new character, just didn't buy the cheerdaddy/realdaddy theory, and thought it was too early to meet Linderman.
So yeah....mostly a lucky guess.
Suppose this episode put the final kibosh on the theory that cheerdaddy was the one with dampening powers too. Looks like it's definitely the Haitian.
