Scission

Six/Rose; Nine/Rose; Part Four of the Prompts series. Since the incident with Pete, the Doctor has been acting strangely, but before Rose can do anything a man in a ridiculous outfit appears in the TARDIS, who happens to be a past version of the Doctor. He's rude, he's annoying... and he seems to be flirting with her. Can they save the universe while the past Doctor stirs up drama?
