Mulder and pregnant Scully, sitting under a tree in the park, their fingers intertwined loosely, holding each other and laughing. They talk quietly about the antics of their son, who begs them to make sure the new baby isn't a girl.

They dream out loud of the what-ifs of another boy, and she playfully chides Mulder. Just because they are waiting to find out doesn't mean she isn't right. William needs a sister. A girl will smooth his rough, boy edges; just like she did for Mulder.

Mulder laughs.

People around them smile at the beauty of two people so obviously in love. Their joy is infectious. A little girl giggles and tugs on her momma's skirt, asking shyly if "that pretty lady" is going to have a baby. Her cheeks flush when her momma says yes.

Can she go talk to the baby, she asks.

Yes, but be polite.

Mulder says hello first, smiling at the little girl's inquisitive brown eyes.

Hello, she says, her gaze moving from Scully's baby bump to her blue eyes and back again. Can I say hi to your baby? Scully's hand slides down to her swollen belly; she smiles at little girl.

Of course.

The little girl squats beside Scully and puts her hand against the fabric of Scully's maternity blouse. Hi baby, she says in singsong, her chubby hand moving back and forth.

When she's born, will you bring her to the park, she asks. I want to see what she looks like.

Scully looks at Mulder.

Why do you think it's a girl, he asks, an unstoppable smile playing across his lips. Never lifting her eyes, the little girl giggles.

Why would she be a boy? Melissa isn't a boy's name. It's a girl's name. But she likes 'Little Miss' better.

A tear slides down Scully's blushed cheek and she squeezes Mulder's hand. No one knew of her pet name for the baby. No one except the baby.

I told you he needed a sister.

He kisses her auburn hair and quietly thanks God for both their children; for his beautiful wife.
