2 characters, same location, parallel universe logline help please
One of my main characters leaves a hotel room and when they come back the other main character isn't there. There is no indication they ever were. I'm struggling to figure out how to word the scene heading so it indicates that each character is in the same room at the same time but in a parallel universe so they don't know each other is there. (if that makes sense).
Would be something like?.
INT. HOTEL ROOM - DAY (for one)
INT. HOTEL ROOM - DAY - SAME (for the other)
And then just continue with the action/dialogue for each character as normal and let that tell the reader what's happening?.
It's probably very simple but it's driving me mad not being able to figure it out. Any help would be most welcome, thank you.
