I was actually thinking the same thing in ep2 when he pistol fires on the dudes. He has that menacing crazy unpredictable side + he's the only sorta-masked character = he will become AGE's Char.
And yeah, they definitely destroyed the unit in ep1 to hide its secrets. What I'm wondering is if these monster things are human manned (which I'm sure they are), they must have some damn good reasons to go around blowing up colonies and killing millions of people. Although I'm guessing in ep2 the reason they attacked the colony was for the AGE system since it's the ultimate weapon machine. Needed to lure it out of hiding so they could nab it.
Also ep2 establishes that the true Federation (aka, not the colony government) may be kind of evil/dicks like in SEED, hence why the UE are so pissed.
And yes, the girl is going to be an enemy pilot that he falls for, you know like EVERY GUNDAM EVER (Farah, Four, Stella)

AGE isn't being super original so far

The only original things AGE is currently bringing to Gundam is the 100 year generational war, and the AGE system.
