Along the lines of the Claire/Russell again, I think the last episode where we saw him, really summed their whole relationship all up in the three scenes he was in:
1) He talks to Claire and Ted, and comes off as the kinda crazy artsy guy, talking about how he got hit by a car and ninjas.
2) Claire runs into outside of the bathroom, and with her anger towards him now gone, she is very kind to him, sensing the soft side of him that is still there, and finally apologizes for not giving him credit for the collage thing that got her a showing at a gallery. Touched, the scene ends with him kissing her on the cheek and hurrying away.
3) Finally, minutes later, Russell tries to physically dismantle Jimmy's 7 foot lollipop, acting totally crazed, giving Claire one final reminder of how crazy he really is.
