If it gets to the point where I don't know the name of the person on screen without looking to the dialogue box, then I say there's too many characters ...
Girl: Hi, MC!
MC: Oh, hello ... you!
Girl: Did you remember our date tonight?
MC: Um ... yeah ... sure.
Girl: You don't look so sure! Remember ... I'm Ruby's friend from the dog park? You pet my puppy and agreed to spend time with me because I looked sad.
MC: ((Who the fuck is Ruby?)) I have basketball practice, a press conference, and four other dates tonight ... but I live outside spacetime so why not?
Girl: Great, see you at 8!
MC: Jaime, add this shit to my calendar.
Jamie: YAY MY BF IS GOING TO FUCK ANOTHER GIRL I'M SUCH A CUCK QUEEN LOL
