That would be true, if one assumes that Kimblee is an actual demon, and not merely a man who likes to see the world burn. [Hey, it's a possibility.]

As for Skye... she has refused multiple times now to give a straight answer to questions, instead choosing to nitpick at an irrelevant part of the question or move onto another topic entirely. It sounds to me as if she isn't a very skilled liar, or doesn't feel comfortable doing it.
