I've noticed that everyone who is a couple in that series is paired off in that picture... except Christopher and Samantha who are on opposite sides of the Robin/Chester pairing, and Samantha looks slightly perturbed. Is she just miffed that she didn't get to sit next to Christopher or did they have a little spat?

And it also makes me think of Wildclaw and Lizaki as a couple because they're so close together, even though I know they really aren't.

Get out of my cheese, get into my corn!
