[Well, it's not reality-bending, but Elizabeth can see how snow and ice run amok could be dangerous and ill-received. She doesn't have an immediate answer, of course, but she can at least trouble-shoot this with Elsa.]

I wonder if we could work with Doctor Banner. Perhaps he can create some kind of personal device that could diffuse or contain your ability on your command, instead of having to rely on another person to be around. I imagine if someone can do it independently, there's a way to replicate it scientifically.
