>>21581084just because he seems forgettable for you doesn't he's a bad professor, Elm is just Oak's student so it's abvious that it can't be as wise as him but he i think his job with the whole "pokemon eggs" thing was fascinating the first time because it was related to a new discovery to the world of pokemon and you just took part of it.
He's also more present than Oak during your journey thanks to the Togepi egg and the Pokegear
