Well, that's one of things I was talking about way back when before we started this debate.Both. And I don't doubt that she likes him... And I don't doubt that she cares about himIt is jealousy or annoyance at Chuck being a dolt again and trusting anyone with boobs who smiles at him![]()
But it is possible to love and care for someone in a non-sexual way
I definitely think she had some romantic/sexual attraction to Chuck back in Season 1, back when we were learning about all the drama with Bryce and that big kiss she planted on him before the "bomb" went off.
But as I originally said, I think they're both starting to develop a more platonic friendship, out of necessity if nothing else.
