John was confused, but doing his very best to keep up. It was hard not to doubt every single thing happening before him the moment Rose walked into his life -- if he wasn't dreaming or hallucinating -- but if he was dreaming fighting it would only make matters worse and if he was hallucinating hopefully someone would get him to the hospital eventually.

"Wait, so we're helping them?" John wanted to ask her so many questions, but if there were mind controlled people with evil shoes on their feet, it probably wasn't a very good time to ask.
"What do we do?"
He was clumsy and earnest, but he hoped that might be enough to help whatever was happening.
