Dean had visited you a few times in your universe after he died in his. You were the love of his life in his universe.. and now here you are in another universe friends with his parents the same age as them mid 20s.
he fell in love with you all over again, he’d spend as much time with you as he could not telling you he was John and Marys future son or about his brother Sam. Just that hes a hunter that died and a few things he had to tell you to trust him.
finally Dean was forced to meet John, Mary and the others when the ecrada made its final night and was about to open the portal. Mary used Deans car not knowing who Dean was yet and drove the acrada into the portal then coming back with Dean. Mary rushed into Johns arms and Dean just stood against the impala. John asked, “who are you?”
but before Dean could respond you butted in running over and hugging Dean. After a moment you pulled away remembering you could never touch before he had to save his strength usually to be able to leave clues for John and stuff. Dean noticed the confusion on your face but John spoke before he could speak, “okay now we need a even bigger explanation. Flora you know him?”
