Amy/The Doctor
I'm sorry that River's hurting, Amy, but there are no bad guys in this situation, only impossible people put in impossible positions.
You're angry with me - leave Clara out of this, she's done nothing wrong - and that's alright, because you're protective of your daughter. However, and I mean this in the best possible way, you need to stay out of this and let River and I work this out together. Otherwise all we're left with is side-taking and blaming, which isn't going to do anyone any good!
