Wha... no! That is the absolute worst thing she could do. Don't tell the PRT what happened? That can only make her look bad. It's not going to be hard for them to figure out "Huh. Tentacle girl disappeared from her cell and Normal Girl appeared in her place. I wonder if these events are connected?"
Sveta absolutely needs to tell them "A Hero showed up, asked for permission, then healed me." This casts Taylor in the best possible light. The fact that her power are gone theyd have to assume is a side effect of healing a C53. Now the PRT is free to speculate the worst possible motive for her actions.
