I have to admit I'm not as much into power fantasies (in that context, when it comes to the reason we are all here, very much), I think it would have neat comic relief, and potential for story telling, to just start of with a discussion about magic, where he knows nothing, and then something comes up no one yet understands and he just thinks that makes sense, and then everyone wants to know how he knew, but, you know it, time's up, gotta leave.
Edit: What could also be played upon is Culture Shock. Something in either world one of the cast thinks is kinda weird, or backwards, but upon closer inspection, the same could be said for their world, possibly moreso - only subtly different.
