The Salvatore brothers appear to be having all sorts of problems in season 5 of “The Vampire Diaries.” For Stefan, it’s simply trying to survive while being locked in a safe underwater. As for Damon, it’s dealing with the guilt and jealousy of his girlfriend Elena having a connection to her ex, Stefan.

In episode 2, “True Lies,” viewers discovered that someone removed the safe Stefan was locked in from the water. Unfortunately for Damon and Elena, Stefan wasn’t inside. Instead they got to lay eyes on a man drained of blood and realized that crazy ripper Stefan may be on the loose.

The episode concluded with the mystery of who let Stefan out of the box -- but that will be solved in episode 3, “Original Sin.”

Thanks to a sneak peek video clip posted on E! Online, fans get to meet Tessa -- played by former "True Blood" shape-shifter Janina Gavankar -- the woman who rescued the youngest Salvatore from his watery grave. In the video, Stefan wakes up in a cabin to find Tessa in front of him.

“I don’t want to hurt you, so get away from me before I rip your throat out,” he tells her.

“Hello to you too,” the brunette responds sassily.

While Stefan feeds on a blood bag provided by Tessa, it's revealed that she saved him from burning to death outside a bar earlier that day. (Fans will remember that Silas took Stefan’s daylight ring.) She’s not the one that pulled him from the quarry, however. Instead she’s the one that figured out his location and had the former owner of the cabin they’re in pull him out.

“You thanked him,” Tessa said to Stefan of his savior. “By biting off his head.”

Who Tessa is, why she was looking for Stefan, and why she's helping him aren't yet known -- but will hopefully be answered in episode 3, “Original Sin.”

While Stefan deals with his new freedom and the mysterious Tessa, Damon will be battling his own demons -- jealousy. The CW network released a sneak peek clip that shows Damon and Elena in bed, but while Damon is happily asleep next to his beau, Elena's visibly upset.

“I had a dream about Stefan,” Elena reveals. “It was more than just a pit in my stomach this time though. It was real. It was like I was there with him."

Damon says, “I know I said it didn’t both me that you have some psychic connection to your ex-boyfriend but I don’t need a play-by-play.”

“You’re right, it’s weird,” she says, apologizing and lying back down, but her face shows that she’s still worried.

Elena’s connection to Stefan is something that Damon should definitely be worried about, according to TV Guide. The synposis teases that Elena and her former lover will be “forever linked,” and the theory behind it is the suspicion that “Silas’ first love looks an awful lot like Elena.”

You can catch new episodes of “The Vampire Diaries” on Thursdays at 8 p.m. ET, and look for Gavankar’s appearance in episode 3, “Original Sin.”
