I'm guessing you just pulled the vernacular from all of the other Universal rides, but it is dead on. I agree. I can only imagine how many children will pass through the gates, just tall enough to ride, and then be terrified of entering rides for the rest of their childhood. Oh wait, that was just me. I'm guessing it would be Hagrid - it would make sense, if he was prepping you for "class" or whatever's about to happen.
