Tonight we got to see the progression of Chuck's character. Would first-season Chuck have tried to take down an enemy stronghold (armed, no less) while rescuing the man who was the romantic interest of the woman he loved? Well, probably, but not with such confidence.
Since he got the Intersect 2.0, it seems like every other time Chuck has flashed has been to learn a form of self-defense. He better pray that the Intersect doesn't become corrupted and he loses that piece of the program (although that would make future seasons more interesting as he couldn't fight anyone without it).
While Chuck is as brave as they come, it's still tough to believe he wants to be a spy. He simply wants Sarah, and if he has to become a spy to be with her, then that's what he'll do.
It was nice that continuity is being kept and the mole that Chuck (or rather Casey) shot last week still plays a role in this week's episode.
