It's never been said whether Katherine had a sister or not, but if she did the sister would probably be long dead.
Well in the book her sister is called Margaret but in the Elena doesnt have a sister she has a brother called Jeremy
The Vampire Diaries
Vicki Donovan is played by Kayla Ewell.
Yes she could she could be bonnies sister
Elena has an ancestor who looks exactly like her- a double ganger :)
No, my sister is not a vampire. She is human.
Harry's sister Katherine is about 25 or 26
My Sister the Vampire was created in 2007.
its called my sister the vampire
Yes there was. Luka (I'm not sure if that's how you spell it) was Klaus' warlock. He was working to get his sister back and (spoiler) ends up dying when his father casts a spell, sending him invisibly to the Salvatore house to pull the stake out of Klaus' heart. Katherine catches him and Damon burns him to death. Hope this answered your question!:)
what is the problem in My Sister The Vampire Switched
she is your step sister or one of your parents is a werewolf and the other is a vampire
