Episode: Season 9 - Mother's Little Helper Pt. 1

Dean slammed a book down on the library table with a resounding thud and I flinched at the sound as I stepped into the room before realizing what it was. Immediately, he began to flip through the book, green eyes glued to the pages. It wasn't until I walked over, Roman gurgling happily in my arms, that I knew what he was obsessively reading - Bobby's old Demonology book. I sent a questioning look to Cas who sat in a corner in an old worn armchair but he was too invested in the food he'd filched from the kitchen to notice.

"Babe, what are you doing?" I asked him worriedly, running my only free hand up and down his back soothingly.

"You know what I'm looking for, Park," he stated, never taking his eyes off the pages of the book spread out on the long, mahogany table.

I chewed my lower lip. Truthfully, I had figured that all along. Last week on a mission to find what Crowley called the "First Blade" to kill Abbadon with, the two of them met Cain. Yes, that one. Which would have went fine after he handed over the Blade. The problem? To get the Blade, you had to get the Mark. As in Cain's curse.

Now Dean was stuck with it and still didn't have the Blade since my father disappeared with it. And although it hadn't been that long since it was branded on his skin, we were all starting to feel the after effects. He'd been snapping at us all lately - Yasmin included - and stress levels had since been very high in the Bunker. Not to even mention the stress of still not having taken care of Abbadon or found a cure for Dean. Although Sam and I had still been looking on that front.

"Dean, look, it's going to be fine-" I started when he cut me off abruptly.

"Stop it, just stop! You know it's not!" he snapped harshly.

Just then, Sam walked in, toting Yasmin on his hip. Her hair hung in tiny black ringlets around her face and she giggled.

"Hey, hey, look guys!" Sam interrupted us excitedly.

Dean and I both turned to face him. Sam nodded to Yasmin then and she faced us, smiling her partially toothless baby smile.

"Uncle Sam wants you!" she beamed, pointing at us.

I gaped at Sam and he just grinned over at us, averting his gaze only briefly to send a proud smile to his little niece.

"What do you guys think? I'm gonna use her for pick-up lines," he said.

Dean's eyebrows shot to his hairline and I could just see the steam coming out of his ears.

"You're using my daughter as chick bait?!" he screeched, green eyes hard with anger.

Cas looked up from his bag of Cheetos then, fingers coated with the orange substance and a confused expression plastered to his face.

"I don't understand. Why would you want to bait chickens?" he asked, eyebrows furrowed and blue eyes as innocent as a newborn babe's.

I would've laughed out loud if Dean didn't look like he was about to blow a fuse. But before Dean had the chance to react, I swapped kids with Sam and hoisted Yaz up on my hip. Sam grinned down at his son, cooing at the tiny infant who resembled him so much. I still had vivid memories of the two of us in childhood and Roman was a carbon-copy of his father. I smiled over at the two of them - my best friend and our son. He trudged over to Cas then - who'd by now finished consuming his cheesy morsels - and handed Roman to the angel. Ever since that babysitting gig he'd ha, he'd been surprisingly good with children. Let's just say, ever since Charlie had been away in Oz, Cas was the designated babysitter from now on.

Sam hoisted up his duffel bag onto his shoulder before bidding us goodbye.

"Hit me up if you find anything." he called over his shoulder and I nodded to him in response before he left.

Dean pulled a bottle of beer out of the coat lying on the chair beside him then and I pursed my lips as he started to drink straight from it. One thing was for sure: that Mark hadn't improved his sobriety.

The rest of the day went by fairly quietly as I'd put Roman to bed early on and Cas had left quite some time ago to attend to some "angel business". I was sitting in the library across from a brooding Dean when it happened. Yasmin, clutching a much-too-big teddy bear for her small frame in one hand, stumbled into the library. I smiled at her as she entered and she beamed back at me happily.

"Hi, munchkin, what's up?" I asked, closing the Vampire Diaries book I'd been reading as she toddled over to the table.

But instead of making her way over to me, she went straight towards Dean. I arched an eyebrow in mild surprise but Dean took no notice of her, his eyes drawn to the now-empty beer bottle sitting in front of him.

"Daddy," Yasmin said, anxiously tugging at the sleeve of his dark blue shirt, "Daddy! Daddy!"

That last forceful use of the word finally broke him of his stupor but once it had, there was no going back.

"What?!" he snapped, whipping his head to face her.

She looked up at him, startled by his sudden burst of anger but oblivious of knowing what had caused it as she pressed on, "Daddy, play with me!"

Suddenly, my eyes flicked down and I noticed his hand gripping the table, shaking uncontrollably. Yasmin was still incessantly talking excitedly to him though, still oblivious.

"Dean-" I began in a warning voice, starting to get up from where I sat.

But it was too late. The chair tipped over with a loud clang ringing out, anger hardening his eyes.

"I don't care what you do, just leave me alone!" he roared, instantly regretting the words as they left his mouth.

Yasmin's lower lip trembled in a pout before she burst into tears. I was by her side in a second, kneeling down to gather her crying form into my chest. Shame, guilt, and self-loathing radiated from Dean as I glared up at him. But before I could get a word out, he'd snatched up his jacket, muttering something about "clearing his head" and he was out the door, leaving me alone with just the kids in the Bunker.
