Well you can expect what this upcoming episode of The Vampire Diaries will be all about, just on the title alone. Isobel will return and she is going to wreck a lot of havoc this upcoming Thursday night. She will threaten to kill everyone until she finds and talks to Elena.
There is a great sneak peek promo video at: and it also looks like Damon is going to have somewhat of an intimate relationship with her, or was it from before? Regardless she is going to be a force to reckon with and I wouldn't want to miss it.
