The Vampire Diaries Season 3: Why Klaus's hybrid didn't succeed? Let's guess which is true, Cai Yujie or Anna.

Klaus's hybrid has three conditions for success:

1. Kill a werewolf

2. the last vampire

Kill the doppelganger

However, obviously, the third point did not succeed. This is why Klaus's hybrid failed.

About Vicky and Anna, I think Vicky is telling the truth.

In addition, it seems that the plot of the third season of The Vampire Diaries should be about the resurrection of those dead vampires.
