I think a 4th travelling partner would be redundant. I hated Max back in AG most episodes
It's not that bad. Just give him/her something to do instead of being a stale wall and you have a character.
At this point Oshawott seems like he's only there to be funny, awkward, and cute. He hasn't really done anything otherwise of note.
True. What I would like is if Ash was to bring along Oshawott with him t the next region like he did Aipom and actually use him for training purposes just in case Pikachu drains again.
