In Thursday’s episode of “The Vampire Diaries” Stefan the Ripper is back (you can see the promo from the CW website here) which means Elena’s (Nina Dobrev) ex-boyfriend is about to go on a massive killing spree for a while. Or is he?

According to an exclusive sneak peek given to EOnline, someone not named Damon (Ian Somerhalder) or Elena saves Stefan and gets him to safety. That person is a mysterious girl named Tessa, played by Janina Gavankar (“The League”, “Arrow” and “True Blood”).

In the video Stefan (Paul Wesley) wakes up to Tessa staring at him. By now he knows he’s in his Ripper mode so he tells her to get back. However, she’s come prepared with some blood-blank blood. She also knows he’s a “vampire doppelganger”.

Tessa begins to tell Stefan how she found him. She even includes the fate of the man who helped her pull Stefan out of the water.

“You thanked him by biting off his head,” she said.

Stefan’s new found “friend” produces a lot of questions.

Will Tessa actually help Stefan or make him worse? Could she be his new Lexi (Arielle Kebbel)? Most importantly, where the heck did she come from? According to EOnline, we’ll get a few answers to the last question during the episode.

If Stefan is in what we hope are the good hands of Tessa, maybe Damon and Elena can focus on Silas. Now that he’s teamed up with the Nadia (who we know little to nothing about), they should probably pay him more attention.

“The Vampire Diaries airs Thursdays at 8/7c on The CW.
