How it should have ended:
In their final kiss, Dani ganks John Snow with tears in her eyes as he is the clear threat to her power and she is now expert at the Game of Thrones. No coming back for John Snow this time.
Dani squares off with the surviving Stark sisters. Arya pops out of nowhere to gank Dani ala the Night King only to be roasted by Drogon in mid-leap. Everyone laughs.
Sansa lures Dani and Drogon north where they and their southern armies are defeated by WINTER (after talking about it for 8 years, winter never got its due). Sansa completes the journey from spoiled princess wannabe to QUEEN with progressively rockin' S&M outfits along the way.
