I kinda wish Friendship games ended with Twilight exiting the portal and saying " I need your help!".



Then in the actual finale, we cut to Twilight having been trying to stop Starlight for possibly thousands of years, the exact time she spent in the loop is unknown but she lands in a universe that turned out ok. Celestia thought her student was ill equipped to deal with Nightmare Moon and sent a letter to Sunset, making a deal that if she returned and defeated Nightmare Moon, Celestia would make her an alicorn. Sunset agreed. The battle took two weeks and Sunset went on a quest and recruited the element wielders(Applejack,Fluttershy,Flash Sentry, Rarity, Cheese Sandwich and herself). In the battle the elements were destroyed but Nightmare Moon was killed and Luna was not saved. When Discord attacked, Fluttershy got him to stop his reign. The Changelings and King Sombra are ongoing threats to Equestria, and Celestia gave her life to stop Tirek. It's not perfect but its not as bad as the other timelines.



The alternate Sunset believes that time travel outside of a closed loop(when you are meant to time travel in the first place) is impossible and that Twilight and Starlight are actually being sent to other universes they create. Sunset decides to help and the two send Twilight to the Equestria girls universe, where she recruits her alternate friends to help. It is EQG Sunset that convinces Twilight to try reasoning with Starlight. This succeeds while the EQG(now Pony) Dash inspires her younger self to perform the Sonic Rainboom. Twilight and Starlight are returned as are the EQG characters to their universe of origin, except for EQG Sunset who is returned to Equestria. Starlight and Sunset both join the mane six(with Sunset planning to go back).



If cartoons can have after credit scenes(and they have). There will be one of the alternate Sunset(identified from her counterpart by both being a Pony and showing signs of being partly transformed into a demon while also being an Alicorn, giving her a half demon wing, half angel wing look) is shown to have defeated Chrysalis and Sombra. She then turns her attention to the alternate universes she heard of and begins a crusade to end the reign of the villains in each universe.
