I'm intrigued by this idea that memories can keep people in existence. It keeps coming back to Donna in my mind - if she ended up in a universe where the only way to bring the Doctor to life would be to reactivate her memories of him, what a fascinating scenario that would be.

Amy, for me, has become the main problem with this whole series. Would she really forget Rory that quickly? It suggests that she's very shallow in my opinion. And I found it very painful to watch the Doctor putting all that effort into doing the precise opposite to what he did with Donna.

Other than that, how cool would it be to have Nazreen as a companion? Please?
