I appear to have committed a faux pas.
I saw on a local FB page someone setting up a D and D group. My autistic young adult has wanted to join a group for ages so I signed them up. It wasn't clear in the post it was for experienced players only.
They are meeting for the first time next week to start a new campaign
It has now transpired that the others in the group are experienced D and D ers and two or three don't want my youngster joining as a newbie. The DM says it's ok though.
My youngster like a lot of autistic people has done a bunch of research and understands in theory how D and D works
Is he going to ruin the game somehow? Is there anything he can do to get up to speed before session zero? I am worried the others will be hostile to him and it's the first event he is willingly leaving the house to go to for a couple of years. Would it be better to just pull him out? I am reluctant to if it's salvageable, because he really could do with a regular group like this to get out of the house.
