G-Man talking is probably just Gordon tripping
@matrix what? combine invasion? alyx? dr. vance isn't even married, freeman.
Gordon died during a tragic monorail accident at the start of the game and everything that happens after that is a type of purgatory.
G-man is actually God judging him. But because Gordon is an enlightened scientist he doesn't believe in God so his mind sees G-man as the atheist equivalent to God. A government bureaucrat.
@matrix the entire story of half life doesn't exest and gordon's just laying in a hallway quivering
