basically I want all of the above back.

The show feels incomplete without him, I miss him so much. Isaac is a close second, though. They're my babies. :( <33

Danny period the end

From your list:

1. Isaac - He is still alive and I really liked him.
2. Peter - He was so interesting, and the way he just disappeared was stupid.
3. Allison - I loved her and miss her, but when characters have had a dramatic death scene like hers I prefer such characters to stay dead, it was her story, which means her story have been told, bringing her back would make things rather stupid and weird.

4. Derek - I liked him somewhat, but I didn't really care that much about him, he bored me a lot too.

The rest I have no interest to see again, Erica also because she is dead, and her story was told, well maybe if they explained how she ended up in that situation and how why she died. but honestly it would be waste of time to explain something about a long gone character. It would probably seem really random too.

There is a character from the newest season though that I wanted to see again more than all these really, because his character did NOT get his story told and was recently introduced.

I just love her!
Second would be Derek,
Third: Isaac

:)
