I wish they met.
In my headcannon, many Gen 4 return from suspensed animadion. And Twylight’s the last of the Mane 6 from Gen 4 to awake; broken coz she beleives her pals gone because of her sins such as abusing Spike includign the owl incident, the Marer Do Well and Walking Dead hoaxes, betraying the CMC, doubting Pinkie, prejurciiding Dyscord and Capper as well as Zecora, nbeglecting ehr human pals, trying to rob Queen Novo, and more. And Sunny helps her. And they boind as Celestia and Twylight.
In my headcannon, somethign si9milar to Horse Play comes. And Sunny’s hesitant to tell Twylight of some error she did. And Twylight already knew but sensitively let Sunny tell; remembring her own errors. And she hgus Sunny coz it took courage to overcome fear and doutbs in one self.
