A/N: Blondie47 made an awesome trailer for this fic and you should check it out. She went to a lot of trouble to manipulate the scenes since Emma/Kathryn/Regina share no screen time on the show. Also it was her reminder that made me post a new chapter, so you have her to thank for that too.

"Go Grease lightning!" Emma popped the collar of her jacket as she sung in her best 'man' voice.

Henry not to be outdone jumped up on Regina's couch one foot on the armrest as he struck a pose. "Go Grease Lightning!" He banged his head to the music and copied the arm movements on screen his Sponge Bob pjs not slowing him down even slightly.

Emma grinned. This had been the third time they watched the movie this week. After an oddly tense movie night between the four of them, Henry had got really into it. She wasn't sure if it was because of his limited exposure to pop culture or if Grease was really just a timeless classic. It could also have been the fact that it was the first movie Emma and he had watched together.

"Uh, uh," Emma grunted with a grin. Henry didn't know most of the words but he tried to sing along the best that he could. Emma secretly loved the fact that he wasn't at all shy about singing and dancing with her in Regina's living room. She would hate to see the day when he became a teenager and too 'cool' to hang out with her.

Regina came out from the kitchen wiping her hands on a tea towel. She was cleaning her already spotless kitchen. It was odd for them to be together without Kathryn but Emma had deliberately arrived early to spend some time with Henry and Regina, oddly, didn't put up much of a fuss. Emma could tell she was sick of Grease though. She hadn't enjoyed it the first time.

Regina's eyes narrowed when she caught sight of Henry on her pristine white couch. He knew he wasn't allowed on the furniture. "Henry-" she started.

"-Mom!" Henry called out jubilantly. "Come on! This is my favourite song!"

Regina stopped stunned at being invited into the fun. Emma held her hand out because Henry was getting into his role as Danny and using the couch as his car. He also started air guitar-ing like Emma taught him. The fact that there weren't any guitars in Grease Lighting didn't seem to matter.

Regina smirked and pushed Emma's hand out of the way. With a challenging smirk she launched into the perfect dance routine for Grease Lighting complete with wagging knees and thrusting pelvis. She was able to pick it up in the middle without faltering. Regina might not have liked the show but she was an amazing dancer and Emma had no trouble believing she could pick up the rather simple moves.

Emma's eyes narrowed playfully. She didn't have Regina's dancing ability but she did have eighteen years of loving Grease under her belt. That included religiously practicing the dance moves to every song and having those skills recently refreshed by the kinect. The other woman was going down.

"-Know that I'm not bragging- she's a real pussy wagon-Grease Lightning," Henry sang loudly.

Regina's dancing stopped dead and she turned to gape at her son before menacingly turning on Emma.

Emma's eyes widened. She had forgotten about that lyric and of course that would be the one lyric that Henry actually sung properly. He had Regina's gift for saying the wrong things at the worst time.

"He doesn't even know what that means," Emma held up her hands helplessly. Regina's glare told her that that defence was on shaky ground at best.

"Grease Lightnnnnnning!" Henry finished totally oblivious to Emma's impending death.

"Henry, what's a pussy wagon?" Emma asked peering around Regina.

Regina looked like she was about to have an aneurism. The vein on her forehead was bulging with the effort to contain her rage.

"It's a car that looks like a cat," Henry explained to her slowly. Like she was stupid.

Emma turned back to Regina. See? He has no idea! Her face said. Regina's narrowed eyes told her that wasn't good enough. Emma switched off the tv.

"Hey!" Henry protested.

"All the good songs are over now," Emma grinned weakly at him. "Besides it's your bedtime."

Henry looked annoyed at them both. He stalked out of the room trying to seem imposing but the affect was wasted due to his cartoon pjs.

"Hey, next time I'll bring over Footloose, there's nothing wrong with that," Emma stepped back quickly. She moved behind the couch for protection.

"I am going to tuck my little boy into bed," Regina growled, "Do not be here when I get back."

Emma wanted to protest. She was supposed to meet Kathryn here after all, but seeing the look in Regina's eyes, she was glad for the escape.

"Hey, Emma, can you dance like that?" Henry asked her stuffing his face with popcorn. Regina didn't allow him to eat sweets so they had a mini party at her place. Regina was probably going at Kathryn like a jackhammer right now but Emma didn't mind. Much.

"No, but your mom probably could," Emma said watching Kevin Bacon do his 'angry dance' in Footloose. "She's a really good dancer."

"Really?" Henry frowned taking his eyes off the screen. "But she's so stiff."

"Not on the dance floor," Emma grinned remembering the few dances Regina and she had shared.

"This is nice, huh?" Henry said softly. Emma turned to look at him. "That she's letting us spend time together. I-I guess, she's not so bad..."

"Maybe you should tell her that," Emma slung her arm around him. He hesitated before cuddling back. "And yeah, it is nice."

There was silence as they continued to watch the movie. Towards the end, Emma got up and got a drink.

"-and I'm not a virgin anymore daddy!-"

Emma dropping the glass and it smashed in the sink. Henry peered over the back to the sofa at her. "You okay Emma?"

"Yeah," she called back her voice slightly strangled. She had thought she did good covering Henry's eyes and fast forwarding through the brief sexual bit. She decided to play it cool. "I'm fine," she went back to sit without her drink.

The silence stretched a moment before for Henry reached for more pop corn. "Hey, Emma, what's a virgin?"

She was sticking to Disney movies from now on. "Uh, it's, uh, well," Emma fumbled and Henry just stared at her. He had just been slightly curious before but now with Emma's inability to answer his sixth sense perked up. That sense all kids had when they found out something they weren't supposed too.

"It's what?" Henry asked with a grin.

"I can't really explain it very well," Emma dodged.

"That's okay," Henry turned back to the movie. "I'll ask my mom when I get home."

"No!" Emma cried in alarm.

Henry shot her a smug infuriating grin. Emma couldn't tell if he looked more like her or Regina in that moment which was eerie.

"I will give you twenty dollars if you never say that word again," Emma sighed.

"Fifty," Henry sensed his advantage.

Emma looked appalled at the outright extortion. That was definitely from Regina. "What the hell are you going to do with fifty dollars?"

"Not ask my mom what a virgin is," Henry smirked.

She hated him, just a little. "Fine," Emma said through gritted teeth "now watch the damn movie."

When she dropped him off home he practically ran to the house. Emma didn't trust him for a second and hurried after him not bothering to lock her car.

"Did you have fun?" Regina asked Henry. She was obviously just out of the shower. Emma saw Kathryn sneaking around the side of the house to her own car. The sight made her grin. "Any more odd descriptions that you've learned?"

Henry contemplated the question for a second making Emma sweat. He shook his head and she sighed relieved. "Night Emma," Henry hugged her around the waist.

"Night kid," She ruffled his hair fondly.

"Henry's already seen Grease and Footloose, all's he needs now is Saturday Night Fever and Flash Dance and his education is complete," Kathryn smiled at Emma across the breakfast table at Granny's. It was slow and they were the only customers this morning. "Oh we should definitely watch Flash Dance!"

Emma shook her head, there was too much food in her mouth to outright say no. "Why not?" Kathryn said disappointed.

"Henry's still a boy, all these dancing movies are great but we should at least let him watch something with explosions or we might as well just sign him up to the pride parade now," Emma scoffed. She didn't want to tell Kathryn the real reason she couldn't watch Flash Dance with them. That strangled moan and slack face she pulled when she watch the manic scene was not something she wanted to show her son. Or Regina for that matter. And no matter how often Emma watched she embarrassed herself by pulling that face, every. Single. Time.

"That is so bigoted, especially coming from you," Kathryn said annoyed.

"Why? Just because-" Emma couldn't continue as Kathryn slapped her hand over her mouth.

"Aw! Why didn't you let her finish?" Ruby whined from where she was pretending to clean.

"Because you are a terrible gossip," Kathryn rolled her eyes. Emma licked her palm and Kathryn jerked her hand back looking disgusted. Her face didn't twist that way when Emma was licking her last night and she would have said that if she didn't think Kathryn would kill her with the salt shaker.

The bell rang and they all turned towards it automatically. Mary-Margret froze under their combined stare like a deer in the headlights. Emma looked between Kathryn and her former roommate. Mary-Margret hovered unsure whether or not to leave. Kathryn stood up and grabbed her bag.

"Oh please don't leave," Mary-Margret said her two hands out pleadingly. "I'll go."

"No, I have to run some errands," Kathryn said stopping in front of the school teacher. She forced a smile on her face and placed her hand on Mary-Margret's elbow. "We shouldn't let this get awkward. We're both close to Emma and this is a small town, we're bound to run into each other. Let's be friends," Kathryn let out a laugh and shook her head, "okay that's pushing it. We should at least be civil."

Mary-Margret looked stunned and nodded furiously. It was almost as if her head was a dribbling basket ball. "Uh, yes-yes that's great! I would love that."

"Good," Kathryn nodded letting out her breath. She moved forward jerkily before stopping as if she thought better of it, then before either of them could react, she pulled Mary-Margret into the world's stiffest hug before quickly releasing her. They both looked awkwardly at each other for a tense moment until Kathryn left.

"What was that about?" Mary-Margret asked as she sat down.

Emma shrugged.

"You must be very good in bed to get her to forgive me," Mary-Margret said dazedly.

Ruby's cleaning tray clattered to the floor as her eyes widened. Emma and Mary-Margret both jerked to face her. They had forgotten she was there.

"You're screwing Kathryn?" Ruby screeched to the entire restaurant.
