It was refreshing that her secret was out now. Well, at least the one about her being Amy and Rory's daughter and Eleven knew that she was supposed to kill him. River was glad she didn't have to pretend she wasn't Amy's daughter. Every time she'd had to, it hurt inside. Especially as she knew she was growing closer to the day when the Doctor no longer would have no idea who she even was. But here, she didn't have to worry about the backwards timelines. It seemed they were all moving in the same direction in this world, which was strange to her. Her whole life had been lived inverse to her parents and the Doctor. She got older and they got younger. It was a cruel fate to watch unfold before her eyes, but she didn't have the ability to turn it around.
For the meantime, to get her mind off of unpleasant subjects and knowing sooner or later she'd probably need to properly explain things to the Tenth Doctor, she was meandering through Lawrence. Well, meandering was the wrong word. She was window shopping mostly. Every once in a while she'd step into a store, but she wasn't buying anything. Mostly she just wanted to see things. It was funny how boring a place got to be when one was stuck in it. River wanted to travel to other planets and other times, see the sights like she always had before. But now she was stuck here in the 21st Century on Earth. Kansas wasn't the most lively of places either, so that didn't help the boredom factor.
What did help the boredom was when she heard a scuffle and someone yell Christo. That was a sure sign demons were around. Going on full alert, River made her way towards the alley the sounds came from. She saw three demons moving towards a dark haired woman, one whom River assumed yelled Christo. Now would be an excellent time to say the exorcism. Or at least the first line of it. She knew the bodies were human and she didn't want to shoot them if she didn't have to. Because River carried a gun with her at all times. This time it was carefully concealed in her jacket pocket.
So without further ado, she stood a few feet behind the brunette and spoke the first line of the exorcism. Her Latin wasn't perfect, but it was good enough to get the point across. And it was enough to get the demons to freeze in place. Her right hand slid into her jacket, taking hold of her gun and slowly pulling it out, careful to keep it in front of her and not visible to any potential passerby on the street. It was always a good idea to keep insurance.
