Whatever happened to Paul's Gliscor?

Paul's team in the league may not be as random as we thought.

The Aggron is obviously the Lairon from the Brandon fight. The Ninjask was shown captured in a flashback. The blue Gastrodon may belong to the Shellos that were in that Pluto episode. And Drapion was shown trying to be caught in, "Chim-charred."

Only random one is Froslass.
