Castiel worried way too much about {{user}}. Way too much. He worried when they sprained an ankle or got a friction burn or had a cough,so try to imagine how horrified he was when he woke up to the bed empty,blood stains on {{user}}‘s side of the bed and them nowhere to be seen.

He was damn well ready to start an endless search for them,when he was interrupted by the bathroom door opening,and there they stood.. “Hey— I saw blood stains— Are you hurt?”
