Sera wasn't sure how long she had been there. There weren't any windows, the lights just got shut off some times so she could sleep. She hadn't actually seen anyone, just a hand shoving trays full of food through the slot in the door. It was good food, too, she had to give them that. Meals full of iron and folate and B vitamins, as well as a handful of prenatal vitamins and lots of juice and herbal tea. For the first few days she had refused to eat anything, but she got hungry, and she knew she had to for the baby she was carrying, so she started eating.

She also went over to the boxes and opened them, finding all sorts of designer maternity clothes. Classy stuff in green and black like she liked. She hated that whoever was doing this knew her so well and was treating her so decent. When she finally broke down and put on a green babydoll dress and a pair of black leggings, a voice came from the walls.

"Glad you're enjoying my gifts, Seraphiel."

She looked around. "Gifts? Gifts are given out of love. I'm your prisoner here."

"Do you not like them? I can have them bring you more."

"Not the point, whoever the Hell you are. Why are you doing this?"

"Do not play dumb, it does not become you. You know very well what this is about."

"So what, you're going to keep me here for the next six months? Feeding me vitamins and giving me pretty clothes so you can take my child when it's born? You must be the biggest idiot in the Universe."

"How do you mean?"

"You think that you can just kidnap the mother of Sam Winchester's child and get away with it?"

"Sam Winchester does not scare me."

"Then I was right, you are an idiot."

"Do not anger me, Seraphiel. I could make life very hard for you."

"Whatever you think you can do to me, it will be nothing compared to what will happen to you. Don't believe me? Ask Azazel, or Lucifer, or Michael, or any creature they have ever come across. Oh, that's right, you can't. Because they're either Dead or locked in the worst corner of Hell. You're going to try and convince me that you're smarter and more powerful than all of them? You think that you can fight off the Winchesters, and Castiel, and most likely the King of Hell? That's an awful lot of pride you got there."

"They will not find you, Seraphiel, I have made sure of it."

"Nothing is going to stop them. They will tear this world apart looking for me"

"It does not matter what they do, they will not find you."

"You just watch them." Seraphiel said, but the voice did not respond. She sat down on the bed, looking around, waiting for him to say something else. Suddenly the door flew open, and before she knew it she was surrounded and was being restrained. They tied her to the bed with blackberry vines and someone shoved a needle in her arm. She tried to look to where is was leading, and at the end of the tubing found an IV bag full of blood.

"What…" she forced out, and then saw the red liquid make its way down the tube and into her arm. When it hit her veins began to burn, and she screamed. It was demon's blood. They were feeding her child demon's blood.

Dean was just sitting there, on the edge of the couch trying to think of something he could do, then he felt a sting in his arm. He looked down at it and saw nothing, but then it started to burn all through him. He crumpled to the floor. Castiel and Sam ran in from the kitchen, Castiel drawing him up into his arms.

"Something's happening…to Sera." His hand clenched Cas's shirt. "It burns…"

Cas looked up at Sam, like he was saying he was sorry for what was happening to his brother and the mother of his child. Dean's screams were muffled in Castiel's chest.

"What could do that to an angel, Cas?" Sam asked.

"There's only one thing that they could be giving her that could hurt this much." He lifted his eyes. "They're pumping her full of Demon's Blood."

"Why?"

"They're trying to corrupt your daughter, make her stronger. It won't kill Seraphiel, but she's going to wish it could."

Dean relaxed for a moment, then tensed and yelled again as he got hit by a new wave of pain. "I think they're trying to increase the rate of her growth. They don't want to risk keeping her long enough for us to find her." Castiel said, trying to pull the attention away from Dean. "It means they're scared, or she provoked them."

"I'd say that's my girl, but since this is what it lead to I don't know whether I should be proud that she's pissing them off."

Castiel looked up at Sam, who looked at the angel and then his brother. He got up and walked out, sliding the doors shut and leaning against them, pretending not to hear his brother screaming, because he knew Dean wouldn't want him to see this, and honestly he couldn't stand watching his brother suffer like this again.

Dean looked up into the eyes of his guardian angel, who took his hand. "It's alright, I've got you," the angel said as he looked down into the hunter's deep green eyes full of pain. Dean took a breath, and then the burning feeling came on him again. He squeezed Castiel's hand so hard that if he had been human, it would have broken.

"We have to find her, Cas." Dean forced out.

"We will, Dean. And we'll make them pay."
