You're welcome! But whoops, what an error on my part about River! Sorry about that; I've fixed the tags and the rec.

I admit, the "Miss" didn't make me think River, partially because I never think of her as a "Williams," and partially because if Amy were in a classroom, she'd probably be addressed as "Miss" unless the teacher knew she was married. (I also assumed Amy had just time-traveled and was undercover for some reason in Barbara's classroom … which I suppose would make for an entirely different but perhaps equally interesting story ;) Regardless, I apologize for getting this wrong in the rec.
