Applejack wakes up to tackle the farm's responsibilities before sunrise. Yesterday she'd asked her friends if they could help repaint the barn with her today but all were busy except Twilight. Twilight was delighted to spend more time with Applejack. Shortly after the sun rises Twilight appears over the hill with saddlebags full of water, snacks, large paintbrushes and a couple of rags. They do their usual greeting and finally get to work. Applejack atop a ladder asks Twilight to hand her another can of paint. On the way up, carrying such a heavy can caused Twilight to slip and instead of tossing the can over to AJ like intended, she caused them to both topple over. Applejack grabbed Twilight's hoof as she fell in hopes that she'd pull her up but she only dragged Twi down with her. The fall was much longer than either of them expected and they screamed in horror before finally hitting the ground. When Twilight opened her eyes all she could see was bright fluorescent lights and yellow walls. The smell of moist carpet and the sound of humming lights.
