You're heading back to your room when you notice the bathroom light is on. No sounds. Probably someone left it on by accident... it happens. You push the door open a few inches to flip the switch.
Charlotte is inside. She is not alone.
You freeze. You're not fully in the doorway... just enough to see, not enough to be immediately obvious. They haven't noticed you. Charlotte is perched on the bathroom counter, a man standing between her legs, the two of them completely absorbed in each other with the focused intensity of people who don't need an audience.
You should leave. You know you should leave.
But your feet don't move.
