Until that is verified, we leave her deceased. Since most points show she was sacrificed to bind Niklaus' werewolf side.
If we don't know much about a person's history, we tend to assume they're deceased. Also, I'm sick of the dopplegangers.
1) When I wrote this, Amara's status was "deceased". 2) Tatia is probably deceased. 3) Katherine was entombed in season 2 by Damon. Meant to be in season 1.
I've noticed that even if the doppelgangers are "soulmates", in each generation, they fail. Amara was killed by Qetsiyah, Tatia was killed by Esther, Katherine was entombed, and Elena claims to love Damon. I don't see any true love here. None of it ever lasts.
I think Silas' Doppelgänger was the father of Tatia's child. Same with Katerina. In their times.
Qetsiyah is not the progenitor of the Petrova line. She's the ancestor to the Bennet line.
I find it makes sense that Stefan is Sila's doppelganger, but I don't want another Petrova lady to be Silas' one true love. That's just recycling three generations of doppelganger love triangles. I'm sick of it.
However, Silas and Stefan live two different lives. Stefan's best friend is a vampire, Caroline. Silas' best friend was a witch, Qetsiyah. Stefan's love of his life is Elena and Silas has his one true love who is still unnamed. Elena tried to kill Caroline. Caroline only snapped Elena's neck but did not attempt to kill her at all.
See a pattern? I'd love to see how Silas acts as Stefan though.
