I tend to picture whoever played the part most (so Rachel and Mark and Gen and Matt…)
Makes senes. I dunno why but I was under the impression that Matt and Jake Able (who played Adam) were Michael for the same number of episodes. I’m probably wrong, though.
I do think it’s kinda funny though that a lot of these characters have been played by multiple people, so the Ruby I have in my head may not be everyone’s preferred Ruby.
