While the Mane 5 are in downtown Maretime Bay doing their own things, Misty sneaks away to their Crystal Brighthouse, hoping to attempt to get to the top most floor where the Unity crystals are. And luckily, Sunny Starscout left her mirror locket behind, although it was a misfortune on her part for forgetting it before rollerblading to the downtown area where her Smoothie Stand was currently parked at. And yes, Misty has her fake cutie mark drawn onto her flanks right now, she drew them herself so that she could blend in. Zipp is still giving her the benefit of the doubt but hasn't forgotten about when the lantern went missing.
