Your best G-Man Theory (Possible Spoilers)

[Hawke]

What's your best theory on who or what G-Man is? What does he represent?

As a side note... anyone else wonder why the ending of HL2 was different from the start of Episode 1?

G-Man.

Some theories of who is Gman:

[/b]Time: [/b] Gman is from the future, Which mean he cant tell anyone in the past thing that will have effect on the future, Doing so will cause time paradox and the changing of the future in uncontrollable ways.
I can base its on two scene:
Half Life : (chapter Unforeseen consequences) [Based on chat on HL2EP2]
Gman is telling to eli the thing that will happen next (The resonance cascade), The Gman don’t say anything and only say "Prepare for unforeseen consequences".

Half Life 2 Episode Two :

• Bulleted list When Alyx is in the heal, Gman tell Gordon that Alyx at first was useless to anyone, But he did took her away from Black Mesa, and saving her life. Gman saw her value and did kept her alive, even though they (Gman employer) saw her as "mere child"
  
  
• Bulleted list Gman is delivering (by Alyx) a message to her father
  Gman: When you see you…Father…… Prepare for unforeseen consequences"
  Gman hint, by using Alyx, That something "bad" will happen to when she will see her father, That mean the Gman already know the thing to happen.

Working for Aperture Science?

• Bulleted list Maybe, his action thought Half Life, Half Life Opposing Force, Half Life Blue Shift, Half Life 2, Half Life 2 Episode One and Half Life 2 Episode Two, show his wishing to "kill" and clear every remember of Black Mesa. As Gman rearm the nuke missile that Shephard disarmed.
  
  OR!
  
  
• Bulleted list Gman is working with Aperture Sciences and trying to hide the existence of Aperture Science from the combine, And he may know that if the combine will get the technology of Aperture Science, they(combine) will ruin the whole humanity and ruin Aperture Science.

Also, Do you ever notice that all Half Life games start in a train?, Except to Half Life 2 Episode One
