Ah, I only told Justin this idea, but I think it would be best for her to do something similar to what Aeris in FFVII does, which is just pray. (Or at least, put her hands together and bow down..) Like I said, you don't need to be religious to pray. It can be a very general gesture.
And when you think about it, she can't really do anything else, seeing as that's pretty much the only thing she can do that isn't overly show-off-y...
