Elena had been saved from Demons by Dean and Sam Winchester. Then went on a roadtrip with them during the summer of her Junior year. She was only seventeen then some what wise beyond her years. Dean pushed her away due to her being jail bait several times. That and he had gotten himself into a bit of supernatural trouble. But she knew about the supernatural living in Mystic Falls. Half her friends were vampires. But she wanted to get a way from that. And she did. Once she fell for Dean Elena got the impression that Sam didn't mind the age gap.
When she turned eighteen Dean and her became an actual couple. She wanted as normal as she could have so after that Summer she went back to Mystic Falls High and graduated. The brothers even found time to attend her graduation. She went hunting with them until College classes started. And she managed to joggle college, and hunting and have a relationship with Dean. Things that seemed impossible but she did it. Sam left College she had heard to pursue hunting again. She never asked him the whys.
Elena had graduated Whitmore College in Virginia. She had a degree just in case she ever wanted a normal job. She could be a teacher if she wanted. But somehow she knew as long as she was with Dean that wasn't going to happen. They ran into so many supernatural disasters and each one of them as died at least once. But she was twenty seven now and Dean as thirty five. Sam and her were close. So close they introduce each other on cases as sister and brother in laws.
Elena always played the wife of Dean when they used their fake identities. Even though they weren't married. Though she often times thought about marriage and never dare brought it up to Dean. They were sitting in a hotel room and it was just Sam and her. "So you ever think I'll be able to actually call you my brother in law for real one day?" she asked. It was not a conversation she had with Sam either but she figured it her thoughts had to come out at some point.
