If there is a sequal,what do you think should happen to Kerrigan?

Don't know if its a part of the official storyline, but Raynor and Taldarin did in fact undo the infestation on Stukov with some kind of experimental serum shortly after he was resurrected by the Swarm. This could mean that any infestation is thus reversible, unless I'm mistaken, although the uninfestation process didn't return Stukov fully back to himself mentally.

So yes, I guess it could be possible to end Kerrigan's tyranny by simply injecting her with that serum. But considering all that has happened after her transformation - I dunno, it would somehow leave the storyline kinda empty.
Although her psionic abilities could mean this might not work on Kerrigan that simple.

That too.

SPOILER!!!!!!!

























She got turned back into a human, but at least there wasnt a wedding.
