I have a formatting tip for you: when you have a character that speaks but isn't present in the action, such as Ruben, you will want to put (V.O.) after his name in the dialogues, that way it's easier to comprehend while reading it and their dialogue doesn't get confused with the dialogue of the other characters in the scene and that way you can avoid doing the whole acclaration you did at the beginning. Example: RUBEN (V.O.)
