Applejack stood and looked over the two arguing fillies with a seemingly blank expression. However, after a moment, she cocked an eyebrow and a small smile came over her rather whimsically. While the fillies rolled around on the ground arguing, seemingly having forgot about her and were now focused on fighting each other, the earth pony walked up to both of them, and crouched low to the ground, a vile smirk coming on her face.
"Huh, what's this we got here?" She asked dangerously. "A case of the Blame Game, hmm? Well, alright then, guess there's no helpin' it."
Rainbow Dash had just barely gotten herself up to once again make sense of all the pointless noise going on that kept her from her pegasus sleep, when she witnessed Applejack pounce through the air and tackle both Applebloom and Scootaloo. The orange pony pinned the two small fillies with her lower hooves, and then winked playfully as she dug her front hooves into the two of them, one hoof per tummy, and tickled them relentlessly. Pinned next to each other on the carpet, the two of them broke out into a series of high-pitch giggles, squirming from the sudden attack.
"Heh, I don' care who started it, who thought of it, or who wanted to do it," Applejack said, smiling genuinely, watching her sister and her friend practically beg for mercy. "Cuz ahm' finishin' it. That sound good to you two?"
Applebloom and Scootaloo nodded rapidly as AJ's hooves rubbed against them, causing them to squeak and squirm cutely. After another second, Applejack subsided her attack, and made her way back over to the main mat, where Rainbow was suppressing a happy smile from the warm moment.
"Now, for the last time, everypony in this here room needs their sleep, and pronto," Applejack concluded, allowing the fillies to approach her and Dash by themselves this time. As they did, AJ winked to Dash, and she grinned goofily back.
"Yeah, come on pipsqueak, if you don't get to bed now, you can kiss flying training good-bye tomorrow morning~" Dash smirked, looking nowhere in-particular, but knowing that behind her, Scootaloo was giving a wide-eyed gasp in response. Within seconds, the orange pony dove onto the rug, curled up, and closed her eyes. Applejack nodded at the pair of pegasi, then patted the rug to catch her own sister's attention, as she trotted over.
While Applebloom situated herself between her big sister's front hooves and upper body, the orange pony wrapped her tail about the both of them, and laid her head down. She muttered, "I know it was Scoot, by the way. Heh. Goodnight, Applebloom." before closing her eyes, and drifting into sleep within minutes.
