There was an ongoing debate between Emily and Lucy. It had started when they moved in together and, to that day, continued to rage. It wasn't a fight, per se, but more of a point of contention.

And said point of contention was whether or not Emily owned too many shoes.

Lucy's position was that there was no room for any of her shoes in their closet because Emily's heels took up nearly the entire closet. Emily's defense was that Lucy owned at least as many – if not more – pairs of pointe shoes... (Lucy, of course, argued that her pointe shoes had a shelf life of maybe two performances, if even that. It was usually at that point that Emily began pretending she was deaf.)

They had this debate, on average, once a week...and Emily planned to put the fact to good use.

Lucy had spent a good portion of Saturday afternoon – while Garcia took the girls on a field trip – going through Aurora's wardrobe and boxing up all the clothes that she'd outgrown...mostly to make room for all the clothes that Clara had outgrown.

Emily had taken that time to catch up on paperwork so that they could have Sunday free to spend as a family. Mostly, though, she was refreshing the UPS tracking page and silently anticipating the imminent arrival of her surprise.

Emily startled Lucy by approaching behind her to rest a hand on her shoulder, making her jump at the contact. When she whirled around, her gaze immediately landed on the box in her hands. Brow arching up her forehead, Lucy's eyes flicked from the box to her wife's face.

"Really, Emily?" she asked, struggling to resist rolling her eyes. "Another pair of shoes?"

Emily shrugged as if it couldn't have been helped...and struggled to keep the brilliant smile from crossing her lips.

Lucy sighed, held out her hand. "Well, let me see them," she demanded. (Even if she thought her wife's footwear purchases were excessive, she had to admit she had excellent taste in shoes.)

Wordlessly, she handed over the box.

Lucy lifted the lid, then froze, eyes going wide. She stared at the contents in silence for several moments before her gaze flicked up to meet Emily's.

Emily just nodded, finally letting her grin burst forth.

She clapped a hand over her mouth to stifle the half-laugh, half-sob sound that erupted. She dropped the box to the ground - a pair of tiny baby sneakers spilling out - and leapt to her feet to wrap Emily in an embrace. "You're pregnant?" she whispered against her neck, finally finding her voice.

She nodded.

Derek flung the front door open, his eyes immediately going wide upon spotting who was standing on the front steps. "What are you guys doing here!?" he exclaimed, surprised and just a little confused.

(They'd called Savannah to tell her they would be visiting, but had asked her to keep it a secret from Derek.)

Without answering, Emily immediately wrapped her arms around his neck in a tight embrace. When she pulled away, Clara darted out from behind her to throw herself at him. "Uncle Derek!" she squealed with glee.

Derek lifted the child into his arms, smiling wide. "Well, hello there, Princess... I haven't seen you since your birthday – you're so big!"

"Where's Hank?" Clara immediately wanted to know, ignoring Derek's greeting.

Lucy rolled her eyes, mortified by Clara's lack of manners. "Clara, don't be rude," she scolded gently.

Derek just chuckled, finding Clara's impoliteness charming (mainly because he didn't have to deal with it every single day like her mothers did). "Hank is still napping, but he'll be awake soon. How about you come inside and have a snack while we wait?"

"I'm starving!" Emily agreed readily. "I hope it's your mom's peach cobbler..."

He rolled his eyes then. "Did you fly seven hundred miles just for some cobbler?" he teased.

Emily's eyes flicked over to Lucy's, the two sharing a small smile. "Actually..." she started slowly, "I – well, we – came to share some news."

"News?" he repeated, brow raised as he questioned what kind of news could possibly have warranted them flying two small children all that way just for the sake of sharing something that could just as easily have been shared over the phone.

"Let's go wash our hands," Lucy said to Clara so they could give the two former partners some privacy. She carried Aurora – who was asleep on her shoulder – inside, following Derek's directions, leading Clara by the hand.

Once they were alone, Derek turned back to Emily with an expectant expression. "So, what's the big news?" he asked. "It better be something good or you've come all this way just to ruin my day."

Emily chewed her lip for a few moments, then took a steadying breath. "I'm... I'm pregnant," she announced, brilliant smile breaking free. A beat. "And you're the father. Which is something I never thought I'd say to any man, let alone my best friend..."

"Wow..." he said, eyes wide in shock. "Really?" When he'd agreed to donate sperm so they could try to conceive, he hadn't really thought far enough ahead to the possibility of it actually working and Emily ending up pregnant with his child.

She nodded. "Due in early February."

Then, without words, he wrapped her in another embrace. "I'm so happy for you, Emily." Then, pulling back slightly, he patted her belly. "And I'm happy for you, little Jellybean, because you have the best damn moms in the world."

"Who has the best mother in the world?" Savannah asked, joining them in the doorway with a bleary-eyed Hank balanced on her hip. She smirked at Derek as if she'd trapped him in a corner.

Derek laughed, leaned in to kiss first Savannah, then Hank. "My son, of course," he insisted, "Who also happens to have the best damn father in the world."

Savannah and Emily both rolled their eyes at his cheesy lines.

"I don't know how you put up with him," Emily said to Savannah with a teasing wink at Derek. "I'm surprised you haven't had to widen all the doorways so his ego can fit through."

"Hey!" Derek yelped.
