The Guy: William (played by Jeffrey Dean Morgan)
Type: Tall, Dark, Handsome-but-doesn't-know-it. He's also a tad shy, which makes him all the more charming.
Love him -- or leave him? "Someone who wants a bit of mystery, as well as a challenge, would be attracted to William," says Kuriansky. "But be careful: His shyness may mean he's hiding something. Chances of relationship survival are fair, but you should find out if his sensitivity is genuine first. I give him a yellow light -- in other words, proceed with caution."
