I felt they were writing themselves OUT of a corner. Can't have Chuck hiding in a corner forever if they want the series to continue.
Agreed but they can't go the other extreme either and have a "know it all".
A bit of both, really. They're going to have to take Chuck's dad back underground. A new villain is always good. But they're going to have to figure out what the rules and drawbacks to the intersect 2.0 are.
What made this show great (IMO) is that Chuck is comedic relief in a ongoing spy show - if he becomes a know it all, it may quickly turn into a lame 24.
