'The Big Bang Theory': Sneak a peek at Eliza Dushku

eliza-dushku-big-bang5.jpg "The Big Bang Theory's" deft touch with stunt casting continues next week with a guest turn by former "Dollhouse" and "Buffy the Vampire Slayer" star Eliza Dushku.

Dushku plays an FBI agent who is checking into whether Wolowitz ( Simon Helberg) deserves a security clearance, and that includes interviewing Wolowitz's friends and colleagues. That also includes some unfortunate remarks from Sheldon ( Jim Parsons) that put Wolowitz's clearance in jeopardy, and an attempt by Sheldon to clarify. We're assuming that doesn't help a ton either.

Judging by the photos below, things go a little more smoothly with Leonard ( Johnny Galecki), while whatever Raj ( Kunal Nayyar) is saying appears to puzzle Dushku's character, Angela. Sheldon's second conversation with her is also below.
