Work Text:
- Next time Morgan has Barnaby in a death trap, at the end of their villainous monologue just as they prepare to leave they just add in a quick "will you be my best man?", this without having actually told Barnaby that they and Alex have gotten engaged. Barnaby would be too shocked to properly answer before Morgan leaves but he'll find them at home later to ask for all details of the proposal and of course he'll be best man. (Barnaby might be disappointed at the lack of romantic dinner and well planned proposal but are happy for the two of them nevertheless. He also gushes over the rings.)
- Alex on the other hand doesn't so much ask, instead they just kidnap Ohio to take him suit shopping. While Ohio is getting measured, he asks why he's being kidnapped and fitted for a suit and Alex just casually answers that he needs it as best man.
- Alex is the one being given away at the wedding (regardless of gender) as they a) have parents attending b) want to make sure the world knows they belong to Morgan just as much as Morgan belongs to them.
- Kotetsu is ring bearer.
- If this is while Ducky is small he might be the flower girl/boy.
