With regards to V and Inky, I personally would like to see V return to Inky and throw themselves at their mercy. My thought is while, yes, we should see Inky living a stable and good life without V there, V has grown and I think that sending a message of "No matter what you cannot fix what is broken" would be a really somber note. I want to see the ending note for V be that, s/he has a long way to go, but s/he can still rebuild a relationship with Inky, s/he can still build a relationship with their children.

Other than that, I'm with a lot of what has been said, I want to see The Dark One in the flesh, he is likely the largest player in all this that we still have never seen (flashbacks don't count). I want to see Bloodfeast return to his dinosaur glory.

One thing that I am curious about is regarding the inevitable dissolution of Team Evil, namely who turns on who first. I personally would like to see Xykon turn on RC before he has the chance to betray Xykon.
