The girl in Marshall's bed was talking to her like she knew her. Like she was Marshall, Kate realized finally, through the haze of sleep and confusion and sudden fear that had taken her over. What if she stayed like this? What if she never had breasts again?

"I think..." But she had no idea what to say. 'I think I'm a dude' or 'I think you're my brother, but with tits, but I can't be sure'? Neither of them seemed to sum up what was going on here.

Instead, she continued to explore, fingertips wandering over much wider shoulders than she was used to, up into her hair and then over her face. Everything felt foreign, like she was touching someone she'd never met before. "Marshall, wake up right now."
