[spoilers] Lucas. Just Lucas.

I also think Vaughan is right, Lucas is doing it for Lucas (to protect the event(s) in his past). I think his passion for Maya (or for a relationship) is real up to a point. [From Wylie's post, it looks like THAT scene is in next week's episode.] I don't see the same intensity in her, but I think that's due to her secret (that Ms Rouass managed to blab to the media).
