Cas paced the floor of their hotel room. It was six in the morning and she hadn’t slept a bit that night, despite feeling exhausted from the day before.

“Cas, come ‘ere.” Dean yawned and sat up, patting the sheets beside him.

She sat down on the side of the bed and he hugged her.

“How are you holding up, Baby?”

“I still feel… Odd. A little on edge, I guess. I’ve been trying to figure out what changed this time all night.”

She ran her fingers through her hair.

“Having longer hair again is strange.” She said, absent-mindedly.

“What is it like? Being an angel?” Dean asked quietly.

“It’s almost like being human, but without all the feelings, and senses, and sensations. And humans are a lot smaller.” Cas noted thoughtfully.

She moved into his lap, and he smiled at how much smaller she was now. She rested her head on his shoulder and sighed softly.

“I love you.” He told her.

“I love you too.” She said, and silence settled over the room.

It broke a moment later, when Cas ran to the bathroom, heaving.

Dean’s mouth dropped open in shock, but he recovered quickly and ran to help her.

“Cas, are you ok?” He asked, holding her hair back.

She nodded slowly, taking a few shaky breaths.

“Yeah, I’m ok, just a little nauseous. I’ll be fine.”

“Alright, but I want you to rest, ok?”

“Ok, Dean.”

“I’ll be back in an hour or two with lunch. I love you.”

He kissed Cas on the cheek and left the room.

When Dean got back, Cas was still curled in bed.

“Hey baby, how are you?”

“I miss not having to worry about things.”

Dean smiled sadly.

“That bad, huh? I got peanut butter and jelly and coffee for you, if you’re feeling up to it.”

Cas closed her eyes and shook her head.

“Ok, but tell me when you feel hungry. I’m going to do some research.”

“No.” Cas said quietly.

“What?”

“I don’t want you to do research.”

“Cas-“

“Dean, please.”

“Cas, what’s up with you today? First, you didn’t sleep, despite being so drained, you’re almost human. And you threw up, and almost threw up again when I got you coffee and pb&j, one of your favorite meals. And now you’re refusing to let me do research, which would usually be fine, but you obviously aren’t feeling well, and Baby, talk to me?” Dean said.

Cas sighed.

“I know what it is that you’re dealing with.”

“Ok, what is it?” He asked and she bit her lip.

“A Nephilim. The child of a human and an angel. We aren’t going to hunt it.”

She locked eyes with him.

“What? Why not? Who’s child is it?”

“Mine.”

Dean’s expression hardened.

“How long have you known about this?”

Cas paused.

“How long, Castiel?”

“A few hours.” She admitted. “Dean-“

“Am I-?”

She nodded solemnly, and he placed his hand on her shoulder.

“Hey, it’s not your fault.”

“I- I think I want to keep it.” She said.

“Ok. Alright, Cas.”

He kissed her.

“Thank you, Dean. I love you.”

“I love you too, Castiel.”
