"I hate witches," Dean says for the hundredth time, pulling into the garage of the bunker.

"Well, you're definitely not alone in that," Sam says, twisting to look at you. "How's he doing, Y/N?"

You shake your head, using a cloth to wipe sweat from Castiel's forehead. "Not good. His fever seems to be worse and he's not waking up. We have to figure out what that witch did to him and fast."

"I'll get right on it," Sam assures you. "You take care of Cas. Dean, help her get Cas to a room."

Between you and Dean, you manage to get the unconscious angel turned human to his room. You round up a first aid kit, a bowl of cool water, and several clean cloths.

"I'm going to throw together some food," Dean says. "Holler if you need me, okay?"

You nod, barely hearing what he says. He leaves.

Cas has been getting steadily worse since he was hit by the witch's final curse and you're doing your best not to show it, but you're terrified. You and the blue-eyed man have only been together a few months, but you're falling fast and can't stand the thought of losing them.

By the next morning his fever has broken, much to your relief. He's still unconscious, but at least he's not burning up. Dean brings you breakfast and you share the good news.

"That's great," he says with a grin, looking very much relieved. "I'll tell Sam." he gestures to the plate heaped with steaming food that he brought you. "Eat all of that, kid. We need you at your best."

The food is delicious, so eating isn't a problem. Sam comes in not long after you finish. He's holding a huge, dusty, absolutely ancient leather bound tome.

"I think I found it," he says. "The curse has different levels, according to this. Based on his symptoms, the witch used a pretty high level, but we won't know for sure until he wakes up. Which should be anytime now."

"What does the curse do?" you ask, though you're afraid you don't want to know.

"It de-ages the victim," he explains. "But not physically. Only mentally. It was originally used to help people, actually. Mental regression can be used as a form of therapy, as well as to strengthen trust in a relationship. Each level of the curse regresses the victim further than the level before. Since she used such a high level, I'm estimating Cas will be regressed to between four to eight years old."

Castiel, Angel of the Lord, mentally regressed to a toddler? That's weird even for you guys.

"How do we reverse it?" you ask.

"That's the thing. We don't. The curse is designed to wear off over time. It senses when it's not needed anymore and will remove itself." Sam looks up from the book. "Why would the witch direct it at Cas?"

"I don't know," you answer. But you know. You know all too well.
Cas has been having trust issues for a while. First the Angels, then Metatron, and then Dean kicked him out of the Bunker last year. It's no wonder he's been having trouble trusting you. However, he's been very honest and has told you about his problems. Things are getting better, but maybe the witch didn't think so.

"We're just going to have to wait this one out," Sam says, pulling you from your thoughts. "I guess we'd better make a shopping trip soon. Get some age appropriate things. I'll put together a list and go shopping. Dean can childproof the Bunker. We're probably going to have to lock up all the weapons."
