I'm the MOH in my best friend's wedding. I've known her, the groom and their families for over half our lives. However, last week, the groom's brother, also best man, passed away. The wedding isn't for a few more months but I know for sure they aren't replacing him in the wedding party therefore I will be left to start the speeches. I was feeling the pressure before this tragedy but now I feel like it'll be the elephant in the room without him being there. Any ideas or thoughts on if I should bring him up lightly or what I should say at all? I really just want to start brainstorming and planning out possible scenarios so that even if it is brought up, it remains a happy occasion as much as it possibly can be! Thanks
