This girl here is a Doctor Who/Torchwood OC named Carly Christian Harkness. Yes, she's Jack's daughter, but she's also Rose Tyler's as well. She's going to be staying with Katniss because, well, they're about the same age and total opposites. Carly will flirt with ANYTHING that walks, and some things that don't. If you want to know her entire backstory, check out her profile in the app.
The second is Arthur Pendragon from BBC's Merlin. He's AU because I have it in my head that, after his death, he was allowed to come back once a century to be with Merlin. He's also a skilled swordsman and a prat.
