Popping the balloon for my character
TLDR:
One player is incredibly rude and mocks the theatrical return of my PC to the party citing as a trope although the rest of table finds my short monologue to be pretty neat and had missed my character's presence.
Background:
I took over as DM for this campaign for the summer to put the party through a side adventure in the Underdark -- the regular DM wanted a break. I told him I'd only do it for the summer but he'd have to take it back by September.
Story:
I had been playing an Elven Cleric before I took over the campaign and in terms of story he had gone off for more training for a while. The party was now gonna face a BBEG as they came out of the Underdark a bit more toothsome -- sadly the campaign didn't last until we got the BBEG.
I decided for a bit of flair for the dramatic -- my character would be described as walking through the mists in a village and being there at just the right moment to return to the party. This was also a way for me to re-introduce him such as describing his appearance -- the party actually did miss him quite a bit -- and tidbits on some of the things he had on his person from our previous adventures.
When I got about half way through my monologue -- which was only going to last a few short minutes -- one player loudly made snoring noises and yelled (at the top of his lungs) on how stupid the scene was and how dumb I must be for resorting to tropes. I should mention this player was autistic and thought nothing of being rather rude -- he didn't generally care if you had a problem with it because it was part of him being autistic so it was okay.
I told him it was rude but he still said it was really stupid. He immediately thrust a screen in front of me -- I can't remember if it was a laptop or tablet -- showing me the tropes he had looked up on TV Tropes to illustrate his point. I calmly explained again how he was being very rude and obnoxious -- I kept a calm voice and wasn't resorting to personal insults. I also explained how he had just hurt my feelings and this would have made other players flee the table and feel unwanted.
He seemed to back down just a bit but we decided to call it there as he had turned the tables to essentially say it was now our faults for trying to make him feel bad for "yelling" at him. There was a slight raised tone from some players but we all had known him for years -- tried in vain to work with him on his behaviors -- and people just decided to walk away from that day's session.
