Now that we know Season 8 will be the last call to sink our teeth into The Vampire Diaries, there's one more question we need to answer: How will Nina Dobrev return to the show?

Executive producer Julie Plec told us us that we can expect Dobrev to be there for the Series Finale at least:

“It’s what she and I kind of agreed on when she decided to move on, and it’s what I’ve got in my head. Obviously things can change throughout time, if the show goes on longer than we expect it to, or if we all collectively decide it would be fun to bring her back earlier, and she wanted to.”

(You can read more on that interview here.)

While plenty of hardcore Delena shippers are praying for that a, there's no denying that the relationship wasn't exactly a healthy one. Some fans think that TVD has improved since Elena dropped into her little coma, and that the show's creators should be wary of bringing her back into the mix.

Luckily, Nina Dobrev mastered the art of playing not one but two beautiful dopplegangers (alright, three, but Amara was kind of lame). It's possible that Dobrev might show up to bid the show farewell as the unconquerable Katherine Pierce. We can't really expect the master manipulator Katherine Pierce to stay dead forever, can we?

Here are five times Katherine Pierce proved she was the best at being a bad bitch:

5. When she compelled an entire town:

4. When she killed Caroline:

3. When she stole Elena's body as a last ditch effort to stay alive...

...and it ALMOST worked:

2. When she turned herself into a vamp because she'll do literally anything to protect herself:

1. When she tricked Damon into thinking she was Elena so he would kiss her and then hacked off Jon Gilbert's fingers:

What's your favorite Katherine Pierce moment from TVD? Do you think NDobz should return to the show as Katherine instead of Elena?
