Feeling the stone melt away, Stel grew furious. [She evolves here.] She heard the thought of her knowing Jack liking her. She skid the car around, and stopped, her eyes blazing. [Ok. So when she transforms, she can freeze/unfreeze more w/ stronger bonds, and is powerful enough to inflate AND explode/ deflate and implode. And if she's at her strongest, her mind reading becomes mind influencing.]
Stel stalked towards Carissa, and tackled her. She froze the throat and then pinned her to a wall. Stel wasn't seeing what she was doing. The entire wall of the wooden cabin was turning into stone, melting with the bond on Carissa's neck. "Listen. I'll crush your throat in a second the next time you do this. He'll go to dinner with you. But he'll never be able to love an old lady like you." Stel inflated some of her hair, and it exploded, showing Carissa her power.
