Need some suggestions on my "Nightfall" series's final two entries.

I bet things will turn out different but...
Live:Ashley, Harold, Cooper|Although I'm sure at least one of them will die at some point since the guy in the first two did, and I thought he would live.
Die:I like all the characters at the moment, I guess whoever the villian will be at the end.
What I want to see happen:I think Ashley and Harold should get together, (I know romance isn't the story's theme, but I want it to happen at some point) I also want there to be a sense in the last one that anyone can be offed at any point, (Again hope it doesn't actually happen).
And Finally:
How I want it to end:(This may change par the time it actually does end): I would normally say I want a happy ending, but I think it'd be cliche. I hope it isn't an "It was all a dream" type ending too. What I'd want to see depends on certain factors. If toi think toi might return to the series but aren't sure, end it where it could pick up again but at the same time also be the end. (If that makes any sense) ou if toi honestly believe it will be the big finish, make sure to end it with a conclusion worth getting to.
That's my two cents, I look vers l'avant, vers l’avant to lire more.
