Apooja!

Rarity, a white pony with a purple mane, stands in a library, her expression shifting from a smile to a frown as she looks at the camera. The scene cuts to Pinkie Pie, a pink pony, who smiles and then laughs while looking at Twilight Sparkle, a purple pony with a blue and purple mane, who looks at her with a gentle expression. The sequence ends with Applejack, a yellow pony with a blonde mane, looking at a glowing, heart-shaped object on a shelf.
