Int. Sheldon and Amy's apartment.
Amy sits on the kitchen chair with Stephen on her lap. She reads him a book.
Amy: Look Stephen, this is a mama bee and a baby bee. They fly together to the next flower.
Stephen giggles and points to the flower.
Amy: Yes, that is a flower. Now, show me the mama bee.
Stephen point at the mama bee, looks at Amy and smiles.
Amy: And now, try to say it. Mama. Say Mama.
Stephen giggles.
Sheldon carries a box into the living room and unpacks it on the sofa table.
Sheldon: Look what I got. A brand new toy train. This is some concentrated fun, I love this so much. I cannot wait to build it up.
Amy: Sometimes I wonder who is the kid here, you or Stephen. Cause normally the kid has the most toys.
Sheldon: You will love this, too. It's the Polar Express. It's magical.
Amy: You already have the Hogwarts Express. Why cannot all trains go to the same place? Especially when these places are "magical" anyway?
Sheldon: Why would the Polar Express go to Hogwarts? You should really spend more time with someone who knows how to use words.
Amy: I am teaching him. I try to make him say mama. Say it Stephen, for mama. Say your first word, honey.
Sheldon: Maybe he would, if you weren't bore him with honey and bees talk.
Amy: Unfortunately, there is no story about a superhero bee.
Sheldon: Oh you mean Bee-Man? Well, there are better superheroes, so he basically doesn't really exist. You are right. Let Stephen get over here, he can help me with the real fun.
Stephen smiles, and claps his hands.
Sheldon: See, he is a smart kid, he knows what is the right thing to do.
Amy: I want him to talk. Why can you not say Mama? Only once, for me, please.
She turns around Stephen, that she can look at him. He continues to smile.
Amy: You are my honey. Sweet as the bee's.
Sheldon finishes placing the tracks on the table, and puts the train onto them. Stephen turns around, moves like he wanted to go to the train.
Amy: Okay, I will let you go. But I am not ready to let you go yet. Why don't you want to be with your mama anymore? I am your mama.
She lets Stephen on the floor and he crawls over to Sheldon. He uses the table to stand up on his feet, looking what Sheldon was doing.
Sheldon: That is the Polar Express. Much better than your mother's book, isn't it?
Stephen giggles and points at the train.
Sheldon: It goes to the North Pole, were Santa Claus lives. In two weeks, he will bring you lots of presents.
Amy: I will dress Stephen like an elf. He will look so cute.
Sheldon: Only because he is tiny? Leonard should be the elf, but elves are hard-working. Well, so maybe not Leonard, maybe Bernadette.
Amy: Shall I dress him as Baby Jesus? We could be Maria and Joseph. Your Mom would love such a Christmas card.
Sheldon: If we do such a thing, I have to be Santa Claus. I make every kid smile, am I right?
He tickles Stephen's belly and Stephen smiles.
Sheldon: We will better get dressed as the spirited girl and the know-it-all boy. We are driving through the clouds, up in the sky to an unknown destination on Earth. Or do we leave Earth? Who knows where Santa truly lives. North Pole doesn't have to be where we think it is.
Stephen tries to jump up and down. He gets excited and Amy worries he could hurt himself.
Amy: Stephen, be careful.
She rushes to the sofa and sits behind him on it.
Amy: Now it's time we go back to the book, shall we? And then you can say Mama.
Stephen looks at her, and then again at Sheldon.
Sheldon takes the remote for the train.
Sheldon: Shall we get it started?
Stephen smiles.
Sheldon: Here, you can wear my conductor head.
He places it on Stephen's head, it is too big, it covers his eyes. Stephen grabs it and puts it higher, so he can see again. He smiles.
Sheldon: Choo-choo.
The train starts driving all over the table, following the tracks.
Sheldon: It always follows the tracks. That is the beauty of trains, everything as ordinary as it should be.
Sheldon let the train stop. Stephen moves closer to Sheldon. He points to the train and looks at Sheldon.
Sheldon: Shall we go again? Do you want to press the button?
Stephen nods, smiles and pushes the button with Sheldon's help.
Sheldon: Choo-choo.
Stephen: Doo-doo.
Sheldon: Yes, say it. Choo-choo.
Stephen: Doo-doo.
Sheldon: See, he can talk. He knows what is good, as I told you.
Amy: It's not a real word. His first word will be mama. Stephen, say mama. I know you can do it. Mama.
Stephen points at the train, laughs: Doo-doo.
