Half-Life 2 Discussion (Spoilers)

[tombo800]

After playing Half-Life 2 through a couple of times I think that the G-Man is an alien like the Vortigaunts a.k.a. the alien slaves from the first Half-Life (the ones that shoot electricity at you) because throughout the game there are numerous parts where you see the G-Man communicating/talking to the Vortigaunts through a T.V. At the start of the game and as well as the fact that he can move around the place so quickly for example the bit where you get the boat for the first time you drive down the river for a while and you see the G-Man looking at you from a balcony then about 10 kilometers down river hes watching you again as if he somehow beat you there. When you try to follow him he seems to vanish without a trace and what's up with the way he talks? speeding up and then slowing down as if he isn't comfortable with human speech like it says in the prima guide?
