If true, good. Please lets have a companion who isn't an "interchangeable sassy twenty-something British girl". A little bit of variety please Mr Moffat. Even if it was just changing the companion to an "interchangeable sassy twenty-something American girl" it would be a start ;-)
btw I'm not saying Jenna isn't great in the role or anything. Just that it's a role we've got a triffle bored with.
