he was talking to otacon :P

but yeah that was rather nerve wracking. but it was rather dumb as well that they've been there the whole time but they didn't do anything until snake realized they were there. 

Without spoiling MGS4 for you, let me just say the progression of the boss battles just gets worse in that game. Half of your bosses battles are semi-rehashes of MGS1 bosses and have zero of the personality those characters in MGS1 had. You had a repeat of an MGS2 battle. You had one wholy great and unique battle in the end of Act 4, and you had another rehash battle at the end that was acutally fantastic in every way because of how well it closed out the series. Overall though, bosses were a huge fail in that game when putting them up against the first.

To add to this list, or maybe replace something, I need to comment that the moment on the elevator when you're CODECing with Otacon and he can't figure out why the weight limit on the elevator is being exceeded, and then he gets all in the screen's face and realizes soliders are in the elevator with Snake in invisible camo, which ends in a sudden death match between Snake and four soldiers in ridiculously close quarters is just a fantastic scene.
