Set during the Glowin' Up section when Hitch is trying to sing it. Pipp smiles at him and two sing it as a duet and start dancing together, they start to fall for each other and go in to kiss just as Sunny and Izzy run past, accidentally knocking off Hitch's fake wings. Hitch backs away from her and runs after them as Zipp drops the gem. Cut to outside in the alley where the film plays out more or less the same, but then Pipp appears with the gem in hoof and asks Hitch what he was doing. After this, Pipp receives a message on her phone, its a breaking news alert of the gem going missing with footage of Pipp running after Hitch with it, she is now a wanted pony and decides to tag along with them.

The film after this point would play out more or less as it did, just the arguments between Zipp and Pipp are over them making Pipp look like a gem thief.

And maybe during the end where Sunny gets her wings, during the heat of the moment, Hitch kisses Pipp, realizes his mistake and backs away, only for Pipp to pull him in for a deep passionate kiss. (well, as passionate as you could get in a U/PG film).
