Simon's limbs were still shaking from the adrenaline, but he was able to move and walk with the strange man's help
(the Doctor, he'd called himself the Doctor...doctor of what?)
When they were inside the strange ship, Simon thought he had either blacked out or been hallucinating. What had looked like a blue police box was impossibly large inside. "Where did," he tried to ask. "Where did... all of this... how does it fit?"
If Mal had something like this on Serenity then who knew what he could smuggle in that cargo hold.
"Oh," he said when they arrived at the room. "Clean. I need... sutures. Forcepts. My... red bag, medical kit. Just help me lie down."
