Check out the first photo of Katee Sackhoff on Season 3 of The Big Bang Theory. The episode titled "The Vengeance Formulation " will air Monday November 23 (9:30-10:00 PM, ET/PT) on the CBS Television Network.
According to the creator of The Big Bang Theory, Chuck Lorre, "the story is about how Wolowitz has this wonderful woman in his life" after a double-date with Leonard and Penny and one of her co-workers from the Cheesecake Factory. But he can't recognize what's right in front of him because he's mesmerized by fantasies about women from sci-fi. The scene is his mental image of Katee, but she's telling him the truth, that he's missing out on real life."
Here is the synopsis of the episode: "Howard is unsure what to do with his new girlfriend Bernadette, so he discusses it with the guys. However, talking with his friends only makes him take wrong turns."
