Ready to take a walk down Memory Lane, Vampire Diaries viewers?

While last night's episode gave us plenty to chew over (a werewolf can kill a vampire?!? Katherine is from Europe?!? Bonnie can take away the power of Caroline's new ring with just one spell?!?), it's hard not to get excited about next week's installment.

That's because we'll flash back to 1864 again, while Katherine will come face-to-face with Elena. Check out the official preview now for "Memory Lane."
