YEP. And even Silence in the Library!era-River would probably take it, just out of sheer fascination, and possibly out of the belief that if she actually did get in over her head (quite unlikely!) the Doctor would be able to stop her. I LIKE THIS WAY TOO MUCH, in fact, I am really all over River + lots of evil magic.

Oh my gosh, actually Amy and Rory would do a really excellent impression of Frodo and Sam! Except without Gollum around to bite off Amy's finger, Rory just knocks her out and throws the Ring in. And everyone is okay! Or mostly okay. As long as Rory keeps his head that one time Amy gets captured by orcs.

Also RORY VS A GIANT SPIDER, OKAY, I AM STUPIDLY DELIGHTED BY THIS NOTION.
