Do we think Charlie does or does not have basic First Aid training? If alone with someone unconscious from an obvious head injury, would he just leave them in whatever position they fell? Or might he know about putting them in the recovery position? Or would he know, but not dare at that point, fearing to aggravate their condition?
(Another thought: Charlie under stress doesn't always think too clearly. Hmmm. Though he did recall some precision training under great stress in "Scan Man," so.)
All thoughts appreciated.
