We got our first peek at Linda Hamilton (Refuge) as Chuck’s (Zachary Levi) mom in the preview for NBC’s Chuck, but now, we have a real good look at her… and she’s gun happy! The mystery of Mary Elizabeth Bartowski aka Chuck’s mom will be central to this upcoming season of the show and these pics make it even more interesting as Sarah Connor 1.0 appears to be confident using a gun and likely involved in something bigger and unexpected.

Check out the preview for Chuck here.

Chuck premieres on NBC, Monday, September 20, 2010.
