It was morning in Equestria and Twilight makes her way to Sweet Apple Acres, hoping to find Applejack somewhere bucking a tree. As she approaches the front gate, she examines the horizon, not seeing AJ, Big Macintosh or Apple Bloom.
She trots up to the house's front door and knocks. "Just a minute!" Granny Smith yelled out. Five minutes later, the door finally opens. Granny Smith adjusts her glasses before recognizing Twilight. "Ah, Twilight! Good mornin'." She says, greeting the Unicorn before letting her in.
"Have you seen Applejack?" Twilight asks. Granny Smith shakes her head.
"Nope." She responded. "I've been lookin' everywhere for those three. It's like they just up and left." She adds.
Twilight rubs her muzzle with her hoof and lets out a low hum. "I don't believe that they'd just leave without good reason or without telling anypony." She guesses. "But don't worry, Granny Smith. I'll go get the others and we'll help on the farm." She added.
Granny Smith smiles. "Thank ya, Twilight."
Twilight's first goal was Rainbow Dash, and as usual, she was napping on one of the clouds. "Rainbow!" She yells, startling the Pegasus.
Rainbow turns down and faces Twilight. "Oh hey, Twi! What are you up to?" She says, hovering down to the Unicorn.
"You haven't seen Applejack, have you?" Twilight asks.
Rainbow rubs the back of her neck. "I haven't actually. Not since the other day." She answers. "Why?"
Twilight trots away. "Follow me." She orders.
Twilight gathers the others and returns to Sweet Apple Acres. "Since AJ, Big Macintosh and Apple Bloom are missing, I volunteered us to help take care of the farm." She says.
Rarity groans. "I just bathed this morning, Twilight." She whined.
Twilight glares at her. "You can bathe again later, Rarity." She calmly says. "Until AJ and the others return, we help Granny Smith on the farm." She continued.
Pinkie Pie bounces excitedly. "And when they do, we'll throw 'em a welcome home party!" She suggested.
"I'm not sure that would be the wisest idea, dear." Rarity says.
"Yeah." Rainbow Dash adds. "We don't even know why they left." She continued. "For all we know, they might be visiting relatives somewhere."
Twilight cocked her head. "Rainbow, they left in the middle of the night." She noted. "It was either stress related, or... something else." She finished, looking up.
