Max and Caroline are both single
Although Max had some fun with her boy toy Nash, a short-lived dishwasher at the Williamsburg Diner who then tried his hand at modeling, things ended rather quickly when his mother came from Ireland to bring him home.
Meanwhile, Caroline has remained very business focused and appears to be holding out for Mr. Right. In fact, the last time we saw her with a main squeeze was in Season 2 when she hooked up with Andy (Ryan Hansen).
