I sincerely hope the Combine soldiers are NOT clones of Shepherd, or clones at all for that matter. That's too much like Star Wars, along with this talk that the G-Man is Gordon's father.
Theoretically the G-Man already has Barney as an agent within the Combine, but I think he never cottoned on that Barney escaped. I can't see how Shepherd fits in so far but if he returns I like Adios Amigos suggestion that you will only catch a glimpse of him.
I think the G-Man's inside man might be much higher up the ranks, Dr. Breen himself.
