"I'd love for that to be how they'd rebuild their friendship and for Clare to be extremely supportive of Bienna and for Jenna to be extremely supportive of Clare/Eli."
^ Yes please!

You know that's a really good point. Especially when at the end she calls KC out for blaming Jenna. It would have been so easy for her to just agree with him and use it to get close to him again. But she didn't and I think that shows that they could very well be close again. Besides Jess said there's hope. Maybe this is what she means~

"The interactions between the three of them in IYE made me wonder if she wasn't just jealous over Clare spending time with K.C., but also over K.C. spending time with Clare. I imagine it bugged her that Clare was okay with being friendly with the ex, but didn't want to be friends with HER. I think maybe that's why she was such a bitch."
^ whoa! I never thought of it that way, but that makes so much sense. Looking at it that way I can see why Jenna would be so upset. I mean I think we all know Jenna was always jealous of KC getting to be with Clare all the time anyway ;)
