Tom goes to wherever he's needed at the moment in time, whistling 'Light My Fire' while sitting in the background. Presumably he went to the place where the orientations took place, wherever that was. Of course, all this talk of magic and dragons and all that other crap made his head spin; and he was pretty damn smart, so it had to be confusing. Nonetheless, he was stuck here now, so he might as well get used to it and figure out what's what.
