Ok, I think I might be mentally tired, but basically how this is going to work is that the trainers are going to walk into the sanctuary and basically catch one of the myriads of pokemon there, right?

I think I have a good idea on how to have Alex encounter his Gastly to be xP

Surprise "attack" and a certain pokemon getting a face smacked with a ball or two.

Pokeballs I mean. Speaking of which, gonna take ten because of that lil prize xP
