Yeah, there were a couple of moments in this ep where I noticed they really looked alike. Another was in the building in Stuttgart, right after Irina called Syd's name to get her to follow her out. It's amazing how much they actually look like mother and daughter. And she does look like Jack in a way, too, with her ears and the shape of her face. Sometimes I have a hard time believing that Jennifer Garner actually isn't the daughter of Lena Olin and Victor Garber! Talk about inspired casting!
