Episode seven is on its way, then we're onto the third act, the final three episodes of how to be god. Maybe Wash will wheel out his almost-catchphrase - 'I'll be fine'. Maybe George will start punching people again. Maybe Amy has some nice secrets to share with everybody. But the strange thing about Dylan is, that while he was originally just the idiot that hunted road signs, he is now becoming the source of ineffable wisdom. He doesn't have any 'proper' storylines of his own apart from his interaction with the other characters. I didn't originally plan to pair him with Amy, but that's the way things went.
