A/N: thanks for all the reviews. I love that you love this fic… before, I said, let the shockwave begin…well, let the angst…BEGIN.!

Meredith finished her lunch in silence, eating hardly anything, but shooting Alex and Addison jealous looks. She tossed her uneaten food in the trash and left the cafeteria, almost running headlong into Derek.

"Hey," he said, kissing her forehead, "What's wrong?" She looked at the ground, not wanting to give him a reason to distance himself from her. She thought that if she mentioned the child to him, he would go running to Addison. Again.

"Nothing," she said, trying to step around him. He blocked her way. His eyes left hers and focused on Addison and Alex.

"Who's kid is that?" he asked. Meredith pretended to notice them for the first time.

"Oh, I don't know…" she said. She was about to say something else, but Derek was already walking to Addison.

"Hey Addie, who's this little cutie?" Derek smiled at Blaire, who blushed. Derek noticed she had red hair like Addison's and eyes exactly like…Alex! The little girl was a mixture of Alex's features and features resembling Addison's. The tiny child had the same facial structure as Derek's ex-wife.

"This is Blaire," she said, hoping Blaire wouldn't blow her cover again. Alex caught her eye and he knew she wanted to keep them a secret for now.

"Come on, monkey," he said, scooping the giggling girl in his arms.

"Ok, daddy," the little girl squealed. "You don't have to tickle me!" Alex started carrying her away. "Bye mommy!" she called back. Addison groaned and rested her head in her hands.

"I knew it! You and Karev?" Derek was furious. "Well, congradulations. The child has your greatest feature, your hair. And your lips, by the way." He walked away, not even noticing Addison was following him until he heard her stilettos clacking against the rough tile floor.

"You always told me you weren't ready to have children," he said, rounding on her again, not caring that they were in the middle of a hallway. Unknown to the both of them, Alex and Blaire were standing a little way away. "And now you have a kid with ALEX KAREV! How on earth could you have stooped that low? Is this your twisted way of getting back at me? I would have thought going for my best friend was the worst you could do, but you have certainly outdone yourself!" He would have continued, but Addison cut him off…with her hand

She slapped Derek with as much strength as she could muster. Derek staggered, and straightened.

"Listen to me, Derek Anthony Shepherd, and listen well. You helped ruin our marriage. It was not just me. Me sleeping with Mark was just the breaking point. I wanted children. I just wasn't ready when I was an intern. So when I was ready, you were living in the god forsaken hospital. And you know what, yes, I was pregnant with Mark's baby. And I had an abortion, because I wanted a baby with you. You know what I found out in LA, Derek? I can't have children! I cant have children!" Addison had tears running down her face now, and Alex had to restrain himself not to run up to her. Derek moved closer. "Do not touch me," he recoiled. "This child. Blaire, with me and Alex? We love her. And we plan on raising her. And if you want to be dumb enough to piss off your girlfriend anymore, keep raising hell."

Addison walked away. Standing behind her was none other than…Meredith.

"Hello, McJackass," she spat.

Alex wrapped a sobbing Addison in his arms when she walked past him. Blaire patted her on the back and ran her fingers through her hair. Addison gave her a watery smile and Blaire hugged her.

"I'm proud of you," Alex finally said. He had sat in silence for the better part of ten minutes, thinking of what to say, while Addison laid on the bed beside him. Blaire was asleep, pretending she was a cat, on a pile of towels. She had insisted on the towels instead of the bed, saying cats don't sleep on the furniture.

"I'm sorry I didn't tell you about Mark," she said quietly. She furiously wiped her eyes, refusing to cry more.

"You have your second chance," Alex said, gesturing to Blaire, who chose this moment to twitch slightly in her sleep. Addison smiled. She closed her eyes, promising just to rest her eyes. Before she knew it, she was sleeping, barely conscious of the fact that Alex was stroking her hair.

Alex watched the steady breathing of his girlfriend. Her red hair was a stark contrast to the pale blue of the pillowcase. Her hand was resting on his thigh, her creamy skin standing out against his navy scrubs. Her lips were parted slightly and he could hear her breathing, deep and even. Her hair was splayed across the pillow, and a faint smell emanated from it. Maybe, vanilla? He laid down beside her, smelling the fragrance of her hair. He drifted off to sleep slowly, enjoying everything in his life. He jerked back and picked up Blaire. No matter where cats slept, he didn't want her sleeping on the floor. With Blaire between him and Addison, he closed his eyes and invited the sweet sanctuary that was sleep

A/N: R&R. but I really like writing the last paragraph. It was my favorite by far :D
