Elsa has to live, be a bit weird having an Elsaverse without her .... just be Verse then.
Pretty sure there would be riots if Miranda died, Jess is just as popular. Chloe is one of my faves so I can't bump her off.
Damn that's actually a toughy, I wouldn't know who to kill. I guess if it came to someone sacrificing themselves for the others, Miranda would be most likely first to volunteer. She's been close to breaking point with her lack of sleep and the medication is losing it's touch so unless something is found to sort that she'd be the most likely to accept self sacrifice.
Picking any of the guys is an easy out, wouldn't have the same impact. If we're going to lose someone it needs to hit hard.
The biggest shocker would be Elsa with her being the title girl but then again would it just be for shock value or could that actually work long term........ guess it would if you were looking to switch to another group of main girls.
I'd go for those then. Miranda has the popular vote so would be a tearjerker moment and she's the type to go for it.
Elsa for shock value and help moving the "verse" on to new people. Way to keep her around is kill her physical body and her spirit lives on in dreamland. Could still work as a guide to new people and would still technically be the Elsaverse.
If we're talking about certain bad guys though, one still being active, and going out in a blaze of family killing glory then Chloe would be the most obvious choice.
