'Vampire Diaries' recap: Originally...
Stefan says he'll get Klaus back to Mystic Falls. If it works, MtVVS will kill Klaus; if it fails, MtVVS will kill Stefan. Once the brothers are alone, Stefan makes sure Damon knows he didn't agree to work with MtVVS to save Damon. He just did it get rid of Klaus and blow this crappy town. Damon believes this exactly not one bit, and taunts, "Careful, Stefan, your humanity's showing." This infuriates Stefan, who doesn't understand why Damon is working so hard to save him. Damon has to save Stefan, because Stefan saved his life by sacrificing his freedom. Stefan: "Aw. Better be careful, brother. Your humanity's showing." Now it's Damon's turn to be ticked. Fisticuffs ensue. Well, actually, they're one-sided. Damon gives Stefan a sound (if brief) thrashing and leaves him lying in the street.
Early in the episode, Alaric and Damon bring Elena with them to see the cave drawings. While Alaric works with Bonnie to decipher them, Elena approaches Rebekah for some Original backstory, which means we get flashbacks -- featuring (not nearly enough of) ELIJAH!
Before the New World was "discovered," the Originals fled Europe to escape a plague, or possibly the plague. Esther, aka Mama Original learned of this brave, new world -- teeming with remarkably robust people -- from a witch named Ayanna. Buffy fans, raise your hand if you can't not say Anyanka in place of Ayanna. There should only be trolls.
