"Ugh, sorry Em," Henry groans, and steps back from Emma with a sigh as Regina steps into the living room. Looking around, she notices their furniture pushed back against the walls, and her area rug rolled up behind the couch. "I keep messing up," Henry breathes out with a huff.

"No way, kid," Emma disagrees, and holds her hands out in her frame, flicking her fingers toward herself to gesture him back. Henry looks at her skeptically, but takes lagging steps back into her space. Her hands correct his posture quickly, nudging him with her elbow here and there until he rolls his eyes and smiles. "You ever seen Scent of a Woman?"

Henry's frame sags a bit, and he asks "What?"

Emma shakes her head. "Yeah, of course you haven't, you're fifteen." Regina stifles her smile at the scene and leans against the archway, careful not to disturb the picture of Daniel on the low side table beside it.

"It's a movie," Emma says slowly, and drops his hand to turn up the volume on the stereo. The sharp sounds of a violin grow louder, and Emma takes his hand again. "My point is," she says slowly, like she's imparting great wisdom, "there are no mistakes in the tango."

"Good," Henry says self-deprecatingly, as he follows Emma, and watches his feet.

"That's why your perfectionist mom likes it so much," she stage whispers, and turns Henry so that she can look over his shoulder to smirk at Regina, clearly aware she was in the room.

Regina raises an eyebrow in challenge and asks, "Excuse me?" Emma ignores the question and winks at her, taking slow steps with Henry as she counts out loud. "Miss Swan, perhaps you would like to explain what you've done to the furniture?"

"Emma's teaching me to dance," Henry answers with a smile over his shoulder. They turn, and he steps on Emma's foot. "Sorry," he winces at Emma, and then tells Regina, "It's not going well."

"And here I thought you two were supposed to be picking a movie for us to watch," Regina says.

Emma stops them, and shrugs her shoulders to gesture to their position. "Yeah, well we kind of got sidetracked."

"Emma got sidetracked," Henry corrects with a smirk.

Looking over at Regina, Emma says, low, "He said there was going to be a dance at school, and he didn't know how."

"I didn't mean you needed to teach me right this second."

"Nah, too bad," Emma shakes her head, and holds up her arms into a better frame. "Kid needs to learn, right?" she asks Regina.

"Mmm," Regina hums, and crosses the room to sit down on the edge of the couch. "Well, then, let me see how you've done."

"Ready, kid?" She counts out loud, and then directs Henry through the steps. The movements are awkward and slow, but after a few combinations they start to fall into the rhythm.

"Shall I get our movie ready while you finish turning Henry into Fred Astaire?"

"Mom," he groans, but his steps don't falter.

"We could watch Mr. and Mrs. Smith," Emma says, and when they turn she's smirking at Regina. "It's got dancing and spies.Not that you'd know anything about either of those, right Regina?" Regina rolls her eyes at Emma's obnoxious smile.

Henry starts to grow more confident with a few more steps, and Emma refocuses on him as she says, "See! You're getting it. No mistakes."

"You're doing wonderfully, Henry," Regina encourages from her spot. "Emma, on the other hand," she stands, and narrows her eyes critically, "you seem to be a bit out of practice without those classes," she clucks her tongue and continues to circle them.

"Oh?" Emma asks, and before Regina can process it, Emma is out of Henry's arms and into hers, pulling her close. "Would you rather I move back in with Mary Margaret and brush up?"

Emma leads her back, and to the side, and again until she can dip Regina, back. One leg comes up on reflex, and her hand flies to the back of Emma's neck as Emma kisses her, long and deep, and she's a little breathless when they part. Smiling, her eyes glint darkly as she whispers, "Don't you dare."
