I know his masquerade as the President in the future came from eating Candice's brain. I meant his transfiguring the sink water spray into snow globe bits at his mom's house in the present.

I like Candice's power. I like that it's limited to appearances, that she can't actually manipulate people's beliefs (Mr. Bennet recognizes her as not Claire, Micah realizes -- eventually at least, and I've seen it pointed out that he may be so used to the Niki/Jessica split that it took him some time to realize this was a third one -- that something's up).
