Well then, re-write her until you feel she fits better. She hasn't really done anything so there is nothing to be undone. I'm sure you could run a tweaked CS by the GMs, but powers aside, most of this RP is about interacting with random bits of action in between, so focus on interactions. Siya's sheet has nothing really about her powers, I sort of make it up as I go along, keeping in mind what would make for the coolest scene without being absurdly over-powered. We don't get led around by the nose to plot, we must be proactive (but not plot wrecking) in finding our fun.
