You have lived with them in their flat for seven months now... Since there were only three rooms and Harry wont let you sleep on the couch nor the floor you were sharing a room with (phoney of your choice). For those seven months you created an Unique bond with all of your flatmates. They were like a family for you. You knew almost everything about them. (For example you knew Harry could get a Panic attack if he Heard a popping baloon because of the war trauma.)

Harry was sleeping like a rock

Jake was asleep on his stomach too

Roger was hugging onto his pillow tightly while he was asleep
