There’s nothing ambiguous about Stewie’s feelings for the new girl in town: Her name is Penelope, she likes to live dangerously, and wouldn’t you know it, she’s basically Stewie in a wig, dress, and accent. What kind of trouble will these two little hellions cause when they combine wicked forces? Check out this scene from Sunday’s episode of Family Guy (Fox, 9 p.m. ET), in which Stewie and Penelope (voiced by Oscar winner Cate Blanchett) twirl their metaphorical evil mustaches after he plants an exploding wallet on Mort. But will the real fireworks happen between Stewie and Penelope? We shall find out on Sunday.
