Why The Condesce has Serket powers? The Condesce of the old alfa timeline (From wich John and Roxy were from) have got those powers because of Tavrisprite, but in this new alfa timeline Tavrisprite never existed because Vriska is alive. So, I don't understand what originated those powers (Sorry for my english)

The Condesce didn’t get her powers because of Tavrisprite, she developed them on her own by experimenting on herself.
