Dean made waffles and bacon for breakfast. Castiel watched you closely as you ate keeping his arm around you. You couldn't blame him he was worried. You were worried. You knew part of it was because right now Castiel was human and he couldn't heal you if you were getting sick, but you told him that him taking care of you would work too. After breakfast, Castiel asked Dean if you two could relax in his man cave as he called it and he agreed. So for the rest of the day, you and your former angel relaxed and watched movies and shows all day.
Every day was more or less like that from then on. Castiel would help with research when the boys needed but other than that he never left your side. Everything was fine until Castiel started to notice you were getting skinnier. It was alarming since you ate. Castiel made sure to watch as you ate every day. But you were losing weight like you weren't eating. He was scared it would get to a dangerous level soon. So were you. All week you had been fighting a fever. Castiel tried as hard as he could to make you comfortable. You were finally somewhat ok when an intense achiness in your joints started to flare. Soon it got to the point where you where crying out because of the pain and Castiel watched heartbroken. He couldn't even comfort you because even the most gentle touch hurt.
Not able to take it anymore you begged Castiel to take you to the emergency room and he did. Soon you were in a hospital bed and the pain was well under control. They did the usual routine and then took some blood. Castiel never left your side. But you both couldn't fight the feeling that there was something very wrong you both just hoped it could be fixed.
