I have been browsing the internet and discover that many fans are predicting, that in episode 461, (1 epiosde after "Aipom and the King), Someone will capture a Weavile, the argument is that Ash will capture it, Jesse will capture it, or no one will capture it.
If you ask me, Ash will capture it, This epiosde seems like the episode "Charmander, The Stray Pokemon", So I think ash will capture it, also he needs a 4th generation pkemon, since May and Brock have one. Also he will need a stronger pokemon to beat the Battle Pyramid.
Post your theorys.
