"Derek Christopher Shepherd!" Derek hears turning around to reveal that Carolyn Shepherd, his mother, probably already found out about Meredith's pregnancy and flew to Seattle on the first flight she could catch.

"Ma! what are you doing here?" Derek asks.

"Well I heard you're finally gonna be a father! Can I meet this lovely woman that's carrying your child? Meredith, is it?" She asks him in return.

"Meredith is it. Ma, I really love her. She's the love of my life. Perfect in every way possible. But I'm not sure she's ready to meet you" He tells her with a huge grin on his face.

"Nonsense! She's carrying my grandchild!" Carolyn says.

"Fine. But do not say anything rude to her" Derek tells her.

"Now why would I do that? I'm offended you think that I would!" Carolyn asks.

"Because she's under alot of stress right now and your view of her means very much to her" he answers.

"Oh Derek, I was just joking" Carolyn hits him in the chest.

"So, where is she?" Carolyn asks.

"I believe she was sent home because she's reached her work limit. Let's go to her house" He tells his mom.

"You guys don't live together?"

"No, we don't. But we spend most of our time together. I'm building us a house. She doesn't know, though. It's a surprise." Derek explains while pulling out his phone to call Meredith.

"Hey, Mer. Are you home?" Derek asks her.

"Yeah i was just napping." she tells him.

"Well I'm sorry to disturb you, but I'm coming over and there is someone I'd like you to meet." Derek tells her, scared of her reaction.

"Oh. Who is it? I'm so tired. The hospital is kicking my ass." She asks him, slightly upset.

"You'll have to wait and see" Derek answers knowing she's angry.

"You know I hate surprises."

"Well you'll love this one. I gotta go, I'm pulling in right now. Love you and the babies."

"Bye. Love you." She says then hangs up.

"Babies?" Derek's mother asks giving him a confused look.

"I was waiting to tell you with Meredith but I guess I spilled. Twins. We're having twins" Derek tells her.

"Well I'm happy for you" Carolyn says while getting out of the car.

"Hey Mer" Derek says while pulling her into a deep kiss.

"Hey" she says.

"What's wrong?" Derek asks.

"You woke me up from my nap!" she says angrily.

"I'm sorry" he tells her.

"Who did you want me to meet?" she asks.

"Come with me and you'll see" Derek says.

"Fine. But you owe me some really good sex for waking me up from my nap. I've been very tired" she tells him.

"Understandable. Considering" Derek replies while walking out of the kitchen.

"Hi, Carolyn Shepherd. Derek's mom" Carolyn says.

Meredith immediately smiles. "Meredith. Why don't you come in the kitchen. We'll talk." she says.

"Well dear, I better get going to my hotel. I'm pretty tired and I'm sure you and the babies are as well" Carolyn says.

"Nonsense. You'll stay here. I have a guest room" Meredith offers.

"Oh I can't ask you to do that" Carolyn replies.

"You're not asking. I'm offering. Now why don't I show you to the guest room" Meredith tells her while walking out.

"I guess I can say goodbye to the make up sex" Derek mumbles.
