I apologize that Alex might be OOC but I have no idea how she acts...
Alex groaned and rolled over, Matts' voice had wakened her. Usually he just shook her awake but he had shaken her and called her River in his attempts to- Wait a minute... He called her River? Let's fix that. She raised up and looked at Matt who was in his Doctor Who costume, similarly she was in her River Song costume, and upon further inspection Karen and Arthur were in their Amy and Rory costumes. (Respectively) She stood up as Matt kept asking her if she was ok. "Matt? Karen? Arthur?"
Amys POV
"Matt? Karen? Arthur?" River asked. As soon as the words left her lips Rory was up off the steps and over with the Doctor and River. "River," he asked carefully, "Can you tell me where you are?" Rivers eyes lit up and she nodded in understanding. "Oh, we're roleplaying for Doctor Who! I get it now." Rory stepped closer to her. "River, what's Doctor Who?" "The TV show- Duh. Anyway, Arthur- whoops sorry, forgot we were pretending- Rory, why are you looking at me like that?" He asked River one more question. "What do you think your name is?" "Alex Kingston- why?"
