Kat and Sam walked through the door, Kat was incredibly nervous.

"Dean?" she called, her voice echoing through the bunker. She wondered briefly he had bolted while she was gone.

"Right here," Dean called, walking into the library, dismissing her thoughts.

She held up the bag, chewing on her bottom lip. Dean smiled weakly. His smile was more of a grimace.

"Well . . . I'll be back in ten minutes," She gulped, walking away, pausing briefly to look over her shoulder at him before disappearing from sight.

Dean sighed heavily, defeated, collapsing into a chair.

"Dean, what's wrong?" Sam asked, sitting next to him.

"Nothing, Sammy," he sighed again, thinking about getting up and pouring himself a glass of whiskey. He decided against it, wanting his last night with Kat to be as sober as possible.

"Something's wrong, I know you." Sam's brows knit together, wondering what was going on with his brother, "and don't tell me it's the pregnancy, I know it's not just that."

"Sammy, what if she is pregnant? I can't let her bring an innocent life into this world. She deserves to be a mother, I deserve jack shit. I can't tell her not to have it, and I wouldn't." He looked physically pained, his eyes shining once again. "She deserves a normal life."

"You know she won't be happy if she's not with you, Dean." Sam sighs softly.

"Not if she doesn't remember me." Dean's jaw clenched, looking away from his brother. He knew this news would not be received well. Kat was Sam's best friend, aside from Dean.

"What are you talking about?"

"She won't be happy if she remembers me," He shrugs, looking down at his hands.

"Dean . . . what did you do?" Sam asked softly, looking at his brother with growing horror.

Dean clenched his fists, "I made a deal with Crowley. Tonight, at midnight, he's going to erase her memories of us, of this life style. She's not going to remember the demon, she's not going to remember hunting, she's not going to remember you . . . and she's not going to remember me. Crowley is going to create different memories for her so she doesn't wake up having lost four years of her life."

Sam sighed heavily, rubbing the bridge of his nose, "What did he take from you to make that deal? You're soul? The Colt? An Angel Blade?"

"All he wanted was to be able to choose what new memories she had," Dean shrugged.

Sam nodded, sighing again, "I hope you know what you're doing, Dean."

Kat took a very deep, slow breath, eyes closed tightly. The timer had just dinged, and she wasn't sure if she wanted to look at the results just yet.

She wanted to be a mother, holy hell she wanted to be a mother, but she didn't know how well mother hood would translate into her hunting life style. In the end, she couldn't think of a better person to be her baby's father than Dean Winchester.

Opening her eyes slowly, she held the test up.

Two lines.

Shit.

She was pregnant.

Kat walked into the library, both boys deadly quiet. They looked up, hearing her footsteps echo through the silence.

Sam looked expectant, Dean just grimaced.

She cleared her throat, "I'm pregnant." The last syllable cracked, she was terrified how Dean would take it.

After a few long, painful seconds, Dean jumped up, running over to her. He caught her up in a huge hug, spinning her around. To her incredible surprise, he was smiling the biggest smile she had ever seen.

"Oh, Kat!" He laughed, hugging her again.

Sam looked as shocked as she felt, but ended up laughing softly.

"I think this calls for a celebration," Dean winked at her, slinging her over his shoulder. She laughed as he carried her down the hall to his room, watching as Sam shook his head, half laughing, half sighing.

"Hey, Kat, sweetheart, look at me," Dean said softly, hours after she announced the news.

"Yeah baby?" She yawned, turning to look at him. They were on their side, he was holding her tight from behind.

"You know I love you, right?" He asked gently, kissing her cheek.

She smiled, nodding, "Of course I do, and you know I love you too. What brought this on? You're generally not the chick flick type."

"I just needed to let you know, apple pie." He nuzzled his face into her neck, smiling as she sighed happily after hearing him call her her favorite nickname.

"You're a dork." She laughed softly, snuggling closer to him.

He listened as her breathing started to even out, her body relaxing into the bed. A few silent tears ghosted down his face, committing this moment to memory. He knew when he woke up she would be gone, he would never get to see his baby, and she would never remember him. He held her tight, hoping not to wake her as the quiet sobs overtook him.
