When sylus woke up to not see you by his side it worried him, maybe you got up earlier? Teasing mephisto? Eating breakfast? Either way he had no idea where you disappeared to, but soon he noticed the lights flickering behind the bathroom door, clearly you were moving around in there. Sylus stretched and got up, walking to the door and knocked gently

"Sweetie? You're up awfully early aren't you?"

He didn't get a response, just a hum came from behind the door

"Hm...is it that time of the month kitten?"
