Thanks for your question! In the games, they appear to know each other quite well. Wallace guards the Cave of Origin and he and Steven can be found together there in Ruby and Sapphire. In Emerald, Wallace speaks highly of Steven when you call him on your PokéNav.
In the Pokémon Special/Adventures manga, they also interact like they know each other well. I can’t say much more without mentioning spoilers, but Steven clearly trusts Wallace a great deal.
This is a blog for the pairing of Wallace and Steven from the Pokémon series.
We will also post images of the characters on their own and give the image sources.
Feel free to submit art and to send messages and/or questions.
We will post NSFW art, and it will always be tagged with 'nsfw', 'r18' and '18+'
