Yep, Ianto's really not going to be happy that Kelis was messing with Jack's head. at least Jack managed to get free of her influence though.

More interestingly, why can't Ianto or the Doctor see or feel the mythological beasts? I thought at first that it was their Time Lord DNA, but if Kelis can't see them either, that rules that out. Floxy is the odd creature out. He definitely exists, everyone can see him, so why did the mythical beasties start showing up just after he appeared?

Like I said before - something definitely fishy.
