Was Emmet gay?

By your logic, he should not be gay because he never made a move on Howard

Remember Howard telling them no touching, and how bad he freaked out when Michelle touched his hand during that first dinner? I'm guessing they both decided to play it safe. I sensed a connection between them, but taking things further was not a good idea with Howard around.

He flirted with her, He was making all those corny jokes. Plus Howard was totally flipping out anytime he made any play or game with Michelle

I sensed no connection between Michelle and Emmit. Watching now.

I felt like they developed a friendship and trust as the movie went on, but a lot of it was driven by the circumstances/fear.

I don't feel like they had much sexual chemistry, but they had a nice rapport.

Duh. You missed the part where he met his boyfriend in the bunker? They got hitched in there and everything. His man-on-man love scene was pretty hot.
