You really have got the same memory loss he does, haven't you...

Doctor, I've never hated Michael. We didn't get on a first, it's true, but I never hated him even then. And we've been together for months, whatever you remember. Or don't remember, as it looks like. I left the TARDIS a couple of days ago, and you did drop me off at Cross' house. You picked Tieria up too.
