A new doctor. A new body. Isn't that strange? Maybe that's why I can finally let go of Rose, and maybe now he can too. My friend Katie made the excellent point that all recent companions have been compared with Rose, and personally, I didn't warm to any of them in the same way. But now? A whole new body, a new companion, and in the words of Matt Smith: She's a ten.
Maybe that's just my thing for redheads cropping up again.
