For Rauch, the sequence represents the ultimate extension of one of the character's defining traits: the contrast between Bernadette's diminutive stature and her intimidating side. "There were trace amounts of angry [back on 'Big Bang']," he recalls, prompting Lauren Lapkus to agree: "Yeah, she had an edge." "I'm so grateful for Bernadette's voice because voice has always been my way into characters," Rauch says. But more than anything, stepping onto the "Stuart" set reminded her of the excitement she felt when she was first cast on "Big Bang" in Season 3. "When I joined 'Big Bang Theory,' I had been a fan of the show," she says.
