Okay, so this is a new wrinkle, but one thing out of it seems obvious to me. Elsa should take Jasmine's bracelet. That should help bolster her powers. If Jasmine wants to play, she shoud go find a magic lamp!
Interesting new chapter. First, we have Olaf (where did he come from?) and then kink play while Elsa is letting a re-attached arm heal. Crazy!
By the way, this story has been a lot of fun so far. Hard to believe that you already have hit the halfway point. I'm curious to see if Anna can truly behave differently than previous bosses or if she has been painted into a corner.
