After a lengthy hiatus, The Vampire Diaries Season 5 returns with a new episode tonight.
It looks to be an interesting return installment, with Katherine out to seduce Stefan and Damon out to resist feeding on Enzo.
But before we look too far ahead, let's take a look back, shall we?
This is a series that has excelled at flashing back to old day (sometimes really old days) in order to surprise viewers with new character information. How did Damon get turned? How did Rebekah come into the picture?
Go back and watch The Vampire Diaries online to relive some of these great installments and see if you agree below with our ranking of the Top 9 Flashback Episodes in TVD history:
9. We'll Always Have Bourbon Street
Not a great deal of new information was uncovered on this flashback episode, but it featured Lexi and New Orleans. Has to earn a spot on our countdown for that reason alone.
8. The Cell
Why did Damon turns off his humanity? We learned about his relationship with Enzo on this episode.
7. Children of the Damned
A terrific Season 1 episode. We saw how Mystic Falls turned on its vampire population during the show's second-ever flashback.
6. Because the Night
It's punk Damon! This hour takes us back to the blood sucker in 1970s New York City.
What was Katherine's life like before she became a vampire on the run? We found out on Season 2.
4. The Departed
All about Elena. "The Departed" marked the end of Season 3 and showed us that Elena actually met Damon before she met Stefan.
3. The End of the Affair
We're off to 1920s Chicago on "The End of the Affair," which earns a high spot for one main reason: it introduced us to Rebekah!
2. Ordinary People
What turns The Originals into The Originals? We go back in time on this episode and learn all about the Mikaelsons.
