The next episode of "The Originals" season 3 brings Stefan of "The Vampire Diaries" in the Mikaelson family's realm. Titled "A Streetcar Named Desire," the crossover event will see Klaus dealing with the Salvatore vampire after the longest time.

Stefan will be needing Klaus help to get vampire huntress Rayna off the back of his loved ones. He won't be too keen to help him out though, especially knowing these guys' history, which involves Caroline. He might have to eventually, since Klaus will also require Stefan's assistance.

The trailer for "The Originals" season 3 shows that Klaus and Elijah will be captured by The Strix. "All of us have waited long enough for this," Aya can be heard saying in the background as the brothers are made to suffer.

It looks like the killer group used a magical trap to capture the brothers, who "The Originals" season 3 synopsis teased were made "useless." The duo is in big trouble. "Today, you die. And with your sire lines torn from you, you die alone," a Strix member tells Klaus, who was seething with anger.

With her brothers in serious danger, Freya turns to Marcel and Hayley to help them. She also seeks Stefan's aid in getting Klaus and Elijah out of harm's way. The Strix has prepared for the two's capture and it certainly won't be easy to break them out.

In addition, Aya has already managed to break the sire line bonds, making Elijah and Klaus easier to kill. With their eagerness to see these two dead, Freya is going to need all the help she can get to save his brothers.

The promo for "The Originals" season 3 also sees glimpses of Davina, who is now putting her plan to bring Kol back for good in action. In the previous episode, she reluctantly set this aside to help Marcel, who promised that he'll help her summon Kol. Now that's all said and done, Davina has his full attention to keeping Kol's resurrection permanent.

"The Originals" season 3 episode 14 "A Streetcar Named Desire" airs Feb. 26 at 9 p.m. ET on CW.
