The Doctor stood in front of the door to the Tardis, nervous in front of two of his friends. Elena smiled at him the same as he had done when he'd stood at her door, and he was suddenly grateful for wanting to jog her memory. She was a good person, and although she might not recognize him the next time he needed her help, if he did; he knew she would help, and that she'd always be worried about him. The Doctor looked at the both of them standing beside each other, and how perfectly they fit.
"What will you do now?" She asked.
"Oh, go places, do things, save people." He replied nervously. "Not sure about it otherwise." He admitted. "Elena continued beaming at him and took his sleeve in her hand.
"Well, I hope you'll be alright by the end of whatever it is you end up doing." She replied. The Doctor smiled at her and kissed her cheek. He pulled away and stared at her.
"I'll miss you Misses Elena Salvatore." He said and she stared back at him.
"I never got the chance to ask. When you showed up at our door, you acted like you already knew me. Did you?" She asked. The Doctor smiled.
"Yes, I did. Back when I had a different face." He replied. Elena stared at him in confusion. "It was before you were a vampire. A little before you found Stefan and Damon, too. I was at one of your father's parties, and we ended up talking because I wasn't there for fun, I was there to stop a shapeshifter. He was trying to take over the town and I enlisted your help, we stopped the bugger before he ever got his votes for mayor. And then I thanked you and took your memories of the man being a shapeshifter, but you wouldn't have forgotten my face." He explained. Elena studied him for a second and then hugged him.
"Thank you." She said
"No problem." The Doctor replied and then Elena pulled away, and Damon held out a hand to him. The Doctor took it in surprise and shook it. Then Damon let his hand go, and the Doctor got a proper look at Damon and Elena, side by side. This was the couple that just saved people from dying in a church, and they did it together.
"You two," he wowed. "you two are meant to be together. And that's coming from a Timelord." He said and looked at Damon. "You were inspired by your love to do the right thing and save those people," then he turned to Elena. "and so were you." He added. Elena beamed at him and looked at Damon who smiled back at her. "You two are soulmates. And I'd know. Having a soulmate myself and all." Elena looked at him. "Found her while she was having trouble with some cybermen. I convinced her to not kill the woman who set them on her, and that's saying something."
"Oh, you mean River?" Elena asked. The Doctor turned around and faced the door, then as he was about to open it he looked back.
"Don't forget to keep cherishing each other." He murmured to them and then opened the door, closing it after him.
I know the River part didn't make much sense, as River didn't come into the Doctor's timeline until Nine, but now with River meeting earlier versions of the Doctor and all, maybe it's not so far-fetched. I did have a dream about this after all, more often than not these little tidbits don't make sense.
