(Right? I'm kind of curious what ends up being the problem at this point.)

I like that idea, the two could happen to be attending the same event. The professor could be talking about Pokemon breeding, possibly more specifically the different egg types and how two pokemon not in the same breed could still create an offspring. 

We can go with Hoenn, though any changes made in Alpha Sapphire are at a loss to me at the moment. I've had the joy of having to pay for my own tuition for the past year, so there's been less video game funding my way. But, I have played Sapphire (3 times, I believe), so I know the original Hoenn region fairly well.
