Well, first of all, S5 and S6 never happened.
Then picture this.
Everyone’s at Jo and Alaric’s wedding (which should’ve happened in the series finale). Jeremy comes back and everyone is reunited. Damon and Elena share a dance with one of their songs playing in the background. Stefan and Caroline officially get together and we get shots of all the endgame couples.
Damon and Elena decide to leave Mystic Falls for a while to travel the world for the summer.
“You sure you want to do this?”
Everything Has Changed by Gavin DeGraw starts playing with a montage of everyone being happy as fuck because everything is finally okay after all the hell they’ve been through individually and as a group.
There’s a shot of Damon’s camaro speeding away and leaving Mystic Falls, paying tribute to 1x11. Flash forwards of everyone’s life later on. Caroline’s in New York on a broadway show or something. Flash forward to Jo and Alaric on the day that their twins are born. Everyone is in the waiting room, waiting to see the babies. Caroline bought them a whole bunch of baby clothes and Stefan’s looking at her like she’s the sun. Jo hands a baby over to Elena after they tell her and Damon that they’re the godparents. There’s a close up of her hand and we see a ring, insinuating that she and Damon eloped some time while they were away. No big deal is made about it.
The episode ends with Damon and Elena on the hood of their camaro, looking at the stars on Wickery Bridge. Elena’s cuddling into his side, like when she woke up beside him in 3x03, except she smiles up at him and stays there. They’re talking about everything and nothing. Then Damon brings up the look in Elena’s eyes when she held Jo and Ric’s kid and asks if she wishes things were different. Then she tells him that it’s a nice thought, but she loves her life now. Her life with him. And she’s happy. Then Damon looks at her, finally believing that he’s enough because he can’t doubt the conviction in her eyes. And then he smirks.
“Why wouldn’t I be? I got everything I was looking for.”
Boom. The shot slowly pans to the sky and we get a glimpse of a meteor shower starting.
