Imagine : Damon leaving Mystic Falls without telling Elena goodbye. She moved on to a Mikaelson and a year has passed. Damon is back now in Mystic Falls and sees that Elena has moved on.
( Ps. Elijah had got turn human at that time and that's how Elena got pregnant ).

Where is Elena at little gilbert ," Damon asked with a smirk?

I don't know Damon. I haven't talked to her in a year ," Jeremy lied.

You haven't talked to your sister in a year. Why are you lying to me ," Damon said with a smirk.

Fine. She is in London, England," Jeremy lied.

Why is she in London, England," Damon asked confused?

She lives down there now after you left ," Jeremy lied.

Damn. It's my fault but I'm going to go get my girl back ," Damon smirked before he speeds away .

For a one hundred and seventy-fourth vampire. He is a dumbass for sure ," Jeremy mumbled.

You told Damon that I lived in London, England and he fell for it ," Elena asked as she starts to laugh .

Yes. For his age that he is a dumbass," Jeremy chuckled.

Yeah he is ," Stefan said with a grin as he wrapped his arms around Rebekah.

Are you calling your own brother a dumbass Stefan ," Elijah asked with a smirk as he bounces his and elena's seven-month-old daughter Miranda on his knees.

Yes I am. We all know that he is one," Stefan said with a grin .

I agree with you on that one honey," Rebekah said with a grin as she bounces her and Stefan's (She took the cure and Stefan had turned human ) five-month-old daughter Lauren on her knees.

So. Who is going to tell Damon that Elena and Elijah are married now and they have a child together ," Jermey asked ?

I will ," Klaus smirked .

Are you sure ," Elena asked ?

I'm sure love. You are my family now. it's always and forever in this family and plus I don't like Damon ," Klaus said with a smirk.

Elena smiled at him.

Jeremy sent Damon to London England," Elena said with a laugh.

London, England. Here I come ," Klaus smirked before he speeds away .

Klaus. What are you doing here , " Damon asked ?

I have news about Elena ," Klaus said with a smirk.

What. Do you know where she is at ," Damon asked ?

Yeah I do. She isn't here in London, England ," Klaus said with a smirk.

Where is she at Klaus ," Damon snapped.

She is happy with my brother Elijah," Klaus smirked at the older salvatore .

What. Elena would never , " Damon said with a smirk .

Are you sure about that one Damon? She and Elijah are married now and they have a child together," Klaus smirked.

The smirk on Damon's face dropped.

It's not possible," Damon said.

It is when Elena has a witch friend that can turn Elijah human for a week so Elena could get pregnant by him ," Klaus smirked.

I say my brother isn't happy about this ," Damon smirks .

Stefan and Rebekah both took the cure and they are now human. And they have a daughter together," Klaus said with a smirk.

The smirk on Damon's face dropped .

He wouldn't have taken the cure ," Damon said.

Stefan did bc he loves Rebekah and they had wanted to be a family but now they are ," Klaus said with a smirk.

No one is going to miss you damon salvatore. Not Elena or even your own brother Stefan bc they are living their best lifes without you ," Klaus smirked before he daggers damon.

Klaus watches as Damon's face turns grey and the lines appear .

You won't be needing this ," Klaus said with a smirk as he takes off Damon's daylight ring .

The sun had caught Damon's body on fire.

Goodbye Damon Salvatore," Klaus said with a smirk before he speeds away.
