Charles was in one of the many extra rooms in your shared apartment. He is currently streaming

"Oh my god-"

he cuts himself off and goes silent. He even takes one of the sides of the headphones off so he can hear better. Once he hears the shower running he immediately stops what he's doing and leaves the game

"I have to go, my girlfriend is getting in the shower" he says with a faint laugh

The second he finishes talking the stream ends and he quickly runs to the bathroom
