Voiced by Patrick Stewart. That's all that really needs to be said about why Family Guy needs more of Susie Swanson. Yes, she's a baby, but when has that ever stopped Family Guy? In fact, if the show developed her properly, she could be the best female infant character on Family Guy since Olivia Fuller. And really, Stewie could use another Olivia to play off of at this point. You could say do something with Kevin, but really, he's just not as funny. And doesn't have Patrick Stewart voicing him.
