The Doctor should have known that going to a fancy dress party was a bad idea. He should have refused as soon as River suggested it. Now, he was standing in the control room – dressed as his sixth self – waiting for his wife to emerge from her room. He was considering calling her, when she suddenly appeared, dressed in a grey onesie with a rabbit ear headband perched atop her wild curls and a carrot in her hand.

River took a bite from the carrot, smirking, then asked in her best American accent, "What's up, Doc?"
