Sully may need a refresher course on how to be a proper fifth wheel, but the guy really looks out for his best friend Liz--he deserves a lot of credit for that. He wants things to work between her and Bryson so badly that he's made it his duty to ruin Louis' chance with her...even if it means interrogating him at the dinner table. In front of everyone. And then giving him the stink-eye.
Check out this bonus video from the latest episode of "My Life As Liz," where Sully scans Louis with a fine-toothed comb. He doesn't want to miss any red flags like, say, a criminal record or vats of vampire blood hidden in his hipster jeans.
