Was this the last we'll see of Thirteen on 'House' (Mon., 9PM ET on FOX)? At least the show didn't kill her off -- or worse -- for her departure. In fact, it was one of the more surprisingly gentle character exits, though House seemed pretty confident that he hadn't seen the last of her.

Thirteen revealed that she's in a relationship now and that she and her girlfriend are planning to travel. Further, she's stepped away from medicine. As House put it, "You decided to enjoy what time you have left?"

The fact that she came to talk to him face-to-face left him that glimmer of hope that she might come back some day. "I'm gonna choose to listen to your actions rather than your words," he said. "It's a bit more honest."

She didn't respond this time with words at all, rather letting her actions tell the story as she turned and walked away. For the last time, though? That is the question.
