I would like it if Claudia came back with Nick but i like Jenny more and want her tro come back but Jenny and Claudia cant both come back, it would be difficult for them as they are played by the same person.

I think the chance is good that we will get back Jenny, because the producers said in an interview that she's definitively not gone forever. As much as I love Claudia, I prefer Jenny- she's so tough and was really cool in series 3.
