According to the logic of this show always remember: Stefan and Elena - or any derivative of them - will always find each other.
Silas and Amara
Stefan and Katherine
Stelena - TVD Dream/Alt Universe
Stelena - TVD Universe
I think this end result is that they will always find each, they’ll always circle back towards each other. That kind of love transcends friendship, love, romance. They are each other’s soulmate, two sides of the same coin.
