when chatting w/ a fandom friend, we end up reducing most of the characters down to first initial unless that's super confusing. so, like with Suits - H = Harvey; M = Mike; R = Rachel; D = Donna.

we've picked up discussing a lot of Phantom of the Opera recently, which presents some additional problems with different actors in different performances of the characters - so they get listed by actor or performance depending on how different they are.
