destinedtofly: I’m just not comprehending what’s going on with this doppelganger business anymore.

And here’s where the mystery of me comes full circle. I created the immortality spell 2,000 years ago. I can never die, so nature needed to find a balance, and version of me that could die. A shadow self. A doppelgänger . -4x23

The curse was bound by the sacrifice of Petrova blood. Witches are crafty with their spells. The doppelgänger  was created as a way to be able to undo the spell. Once a doppelgänger  reappeared, the curse could be broken. -2x09

I’m trying to think of a way I can try and explain this without confusing everyone even more. Personally, I think the mythology that gets involved in this story is the most difficult for everyone to comprehend just because there’s so much lore to try and understand. 

Doppelganger’s are created to be able to undo a curse. With Esther’s spell that she used to turn her children into vampires, she used the blood of Tatia. It was the blood of her doppelgangers (Katerina and Elena) that could ultimately break that curse/create the hybrids/whatever it was, I get a little fuzzy on those specifics…

In the same manner, when Silas created the spell to become immortal, there needed to be a way to break that spell, which would be the blood of his doppelganger, Stefan. 

destinedtofly answered your question: Do I recap the episode now, or have we all almost…

I’m just not comprehending what’s doing on with this doppelganger business anymore.

I think you and the majority of the fandom, lol, and I don’t think I’m helping the situation when I try and make sense of it. 

I’ll try again ;-) haha.
