You were a vampire older than 800 and you once dated Silas the immortal but he was gone for 2000 years and didn’t think he would come back ever and you were walking and you ran into someone and you were I but shocked and speechless since it looked exactly like Silas and you couldn’t believe it

(And Stefan is also a vampire but he’s 171 years old and you didn’t know he was the doppelgänger of Silas)
