[@Lucidnonsense] Christi pretty much can take complete control of the sensory parts of the brain, so that person becomes completely convinced that what they are seeing/feeling/whatever is completely real. Plus she can just turn off their senses to really fuck them up. Her catch is that everything she does happens to her as well. For example, the first time she used her power to escape from her brother, she turned off his sense of balance so that he wouldn't get close to her. Not long after her own sense of balance went away as well.

Right now she's making it so that Danny and Eli aren't seeing her. If she looked up, she wouldn't be able to see them either, though all three of them can still hear each other. She's also going to have a reall splitting headache soon.
