Forum:Adrian Shepard in HL2 Ep.3

Wouldn't it be awesome if Adrian Shepard appeared in HL@ episode 3? I mean like he survived Black Mesa, G-Man is still evaluating him, so he should deserve a role. So maybe like when Alyx and Gordon start to travel they get ambushed by Combine and suddenly Adrian appears still as young as he was 20 years ago and saves their buts? Anybody agree?
