If Dr. Breen needed a host body to survive in the combine environment, doesn't it make logical sense that the gman is from another world (or universe, or dimension, etc.) using a "human" host body to survive in ours? He's an alien dammit.
Hes obviously a male lover.
What do you think happens when gordon is an a "Stasis". I mean..you think gman could resist? lol.
I mean its sooo obvious. Then when gman needs some cash he sends gordon out of the "Stasis" to do something so he gets money.
Sooo obvious people.!
