It's a bunny, Cas.

Sam walked through the bunker, from the library, where Nate was two laptops deep into a game, down through the hallway past the living room (he refused to call it the "Dean Cave" or the "Fortress of… well whatever Dean was calling it) where Morgan and Alice were battling it out on the large screen TV. He smiled as he heard the voices of the four people in the kitchen.

The bunker had never been so alive and it was Easter.

But that didn't stop the regular happenings that went on in his life. NOPE, it seemed to make them worse.

Rounding the corner from the hall into the huge kitchen. He spotted Bee, who had quickly become family and was most certainly going to be part of the celebration, sitting at the table, notebook on the table as Dean and Ali moved about behind the stainless steel counter, preparing dinner.

Cas, on the other hand, seemed to be pacing, and apparently there was a reason for that.

"You do realize I was there when Jesus walked the earth?" He stated and pointedly to which he was met with a resounding yes from the other three people in the room. "But you still insist that this day has something to do with rabbits that lay eggs."

Sam couldn't help but let his grin grow. Ali, who was currently wearing purple bunny ears, turned and looked at Bee, who just shook her head and raised a brow.

"I fail to see what one has to do with the other." Cas continued.

"It's just tradition, Cas." Ali shrugged and Sam watched as she purposely brushed a hand over Dean's crotch to get to the spoon that was nowhere near it and Dean rolled his eyes, slapping at her hand. "The bunny leaves eggs, the kids find them full of chocolate, and then I get the candy. Tradition."

"That's another thing I don't understand." Cas continued to pace yet again. "Why would anyone want to eat chocolate out of an egg? You do know where eggs come from, don't you?"

Everyone stopped and stared at him, thoroughly disgusted.

"They're plastic, Cas," Bee spoke up, "plastic eggs, they come from the store, not from an actual chicken."

"I'm sorry," he said as he looked at her after a moment of quiet thoughts, "you're right, please forgive me."

And that was Cas flirting. With Bee. He had been doing it all weekend but no one had stopped to help him try something different, which was probably okay because the way the two of them stared at each other, it was almost too much. It was almost like Cas and Dean, but that was because they were the same height, not because…

Sam shivered and looked over at Dean, who was watching the exchange with a bit of interest. Maybe Sam wasn't the biggest freak in the house.

"Okay, off the subject of chicken butts and chocolate." Ali snapped, getting everyone to look over at her, but she had that smile on her face, and once she had their attention she shook her head. "Never mind, I got nothing."

"Really?" Dean blinked, staring down at her from where he stood beside her, "after all that, you got nothing? YOU?"

"Nothing on chickens, unless choking one has anything to do with the conversation, like how my hand fits around…" and her voice got very quiet as she moved up onto her tiptoes and started whispering to him.

Sam could see her hand movements from where he stood and even he had a whole body shiver because she was doing the same stroking motion with her hand that she had used on Sam that very morning.

Dean turned bright red. "Okay, okay, you made your point. Knock it off!"

Ali kissed him on the cheek, rounded the corner and went to pour herself a cup of coffee, but not before she paused and kissed Sam quickly before going about her stuff. Sitting at the table with Bee, Ali looked at Cas and Sam and gestured towards the empty seats.

"NO, ut-uh, Sam can help me cook if you're taking a break, short stuff." Dean snapped and Sam shrugged moving over to the sink to wash his hands.

"So, where were we?" Ali questioned Bee and the two eyed Cas. "Oh, yeah, tradition."

"What did you do for Easter, Cas?" Bee questioned.

"We… we never really celebrated anything. Time isn't of import there. Those two-thousand years since my brother was born."

"Half brother," both Bee and Ali echoed without looking up from where they were made Sam and Dean glance up at the same time.

"The familial bond isn't in question here." Cas seemed to be getting annoyed as he finally took a seat next to Bee.

"We're not questioning your… half... brother, Jesus Christ." Ali managed to say without laughing but it was Bee's face that got her.

"You just had to say it, didn't you?" Bee shook her head.

"Oh, come on, when are you EVER going to use that line again? Plus it was an opportune time."

"Big words from a small girl, are you two? Seriously." Bee laughed. And so did Sam, it was great to finally see Ali communicating with someone who wasn't arguing with her and wasn't him.

"Two and a half actually, which gets me thinking," and she turned to Cas, "Do you celebrate half birthdays?"

"Really?" Bee spoke up.

"It's a valid question."

"It's so not!"

"You celebrate a half-birthday."

"So?"

"So therefore it's important."

"Ladies," Sam had to step in, and the two turned to look at him, "how many cups of caffeine have you had today?"

"Clearly not enough," Dean mumbled, "they're still sitting there, being a pain in my ass."

"Heard that, Winchester!" Ali replied.

"She's has her usual three cups by now," Bee smiled and lifted her cup, "fourth tea, thank you very much."

"And clearly not enough powdered sugar." Ali replied and the woman across from her narrowed her eyes. "What, I'm stating yet another fact."

"Half birthdays?" Cas questioned, going back a few conversations which made Bee and Ali look over. "I don't believe I've ever heard of a half birthday."

"Okay, so here's what happens, six months after your last and before you're next is your half birthday, which means cake, ice cream and presents." Ali grinned.

"I'm confused on why."

"Um, cake, ice cream and presents." Ali reiterated.

"I understand that but…"

"Cas," Bee put her arm on his hand, but when Cas finally looked up and stared into her eyes, just merely shook her head. "It's Ali, there is no understanding."

"HEY!"

"I agree." Dean spoke up and Ali twirled to look at him. Dean pointed the tip of the knife in her direction. "You make no sense sometimes."

"I make perfect sense, you just don't understand the logic behind it." Ali shrugged and went back to her coffee, brushing him off. Her eyes bounced up to Cas. "Did you meet him?

"Who?"

"Jesus?"

Cas paused, "no, I was leading an army at the time, but the angels rejoiced when he was born, and celebrated when he was reborn. It was a… festive time."

"Okay, so here's the thing, Easter here is kinda the same thing, people celebrate his rebirth and surviving passover." Sam was surprised at the actual tone of her voice. She wasn't joking, she had no bit of humor in it, she was just… talking.

"The taking of the first borns in Egypt."

"Yeah, that, which by the way, you know that gives me nightmares right?" Ali growled, and that had Sam shifting. "To think that Chuck would be that cruel, the first born, seriously, I would take him on to save Nick…"

"Okay," Dean moved quickly from behind the counter and placed his hands on her shoulders. Sam could feel the shift in the air, he seemed to be stirring things up. "Let's get off the subject of that whole deal."

"Agreed, that was a dark time, " Cas reached across the table and took Ali's hand and between the two of them, her body seemed to relax.

"I'm good," Ali whispered, her eyes roaming, landing on Sam's. "I'm… sorry, maybe it's the moon, sometimes he gets a little uppity."

"Yeah, we all do." Dean kissed her on the cheek and moved back over to stand beside him as Sam took a deep breath, mumbling towards his brother. "You need to take her to the room and give it to her hard. She needs an out."

"Dean," Sam rolled his eyes, "that's not what she needs, just give her a minute."

"You sure?" Dean questioned and Sam only rolled his eyes, giving him a frown, "cause I have no problem taking one for the team and doing it myself."

"Must be out in full force if you touched her and now you're like this." Sam was worried now, and he looked over at Ali. Cas hadn't let her go yet, but it didn't seem to affect the way that he looked at Bee. "We should set them two up."

"Have you not seen the fuck me eyes going back and forth between them, they're pretty much just waiting on an empty room, and three kids that aren't controlling every room in the bunker." Dean snickered.

"You like that they're here, don't you? Her kids?"

"I like that they're all here, Bee too. Family, Sam, the only ones we're missing is Jody and the girls and they said they had other plans, so yeah, I'm loving that they're here."

"It's a bunny, Cas!" Ali laughed and the brothers looked over at the table once more, seeing the look of horror on Cas' face.

"That's… that's just disturbing." Cas frowned and Bee took his free hand.

"Don't worry, I'll protect you from the evil costumed Easter Bunny." She smiled and leaned her head on his shoulder.

"I appreciate that, thank you." Cas leaned his cheek against her hair for a moment and Sam smiled. It was a very human thing to do, but then he cocked it back the other day. "You humans submit your child to that kind of horror? Are you actually trying to set them up for a lifetime of nightmares and therapy?"

"Thank you!" Ali snarked. "Finally, someone gets it."

"Oh, we all get it." Dean quipped. "It's just a matter of how often."

AND that was when the timer went off.

Ali jumped up from the table, Dean turned to grab the pot holders. Cas shifted to stand, pulling Bee up with him as he moved out of the kitchen, never releasing her. Sam grabbed the basket of rolled silverware. Dean placed the ham on the counter, and then grabbed the stack of plates as Ali did the same with the plastic tumblers (they had lost too many glass ones to use them anymore) and they headed out towards the library.

It was time to eat, and they had a table to set.
