easter eggs in gen 5? not too sure. there have been theorycrafters taking tiny details WAY out of context but that's about it.
hell, i'm still waiting on gamefreak to solve those lore holes gen 5 left. who the fuck is the king mentioned in the abyssal ruins?
what's the deal with the ancient ruins in route 4? how the fuck does a castle just raise itself from the ground behind the pokemon league?!
