In the Flashbacks only, I doubt they will show her in the present day.

'The same holds true for the story of Tatia, the Original Petrova, who we should not expect to see this season. That's a story that will only be told if Klaus or Elijah survives into Season 4, Plec explains. "[It's a question of] how many originals are left to tell the tale when all is said and done. If there's any standing, maybe that's a story we'll tell one day," she teases.'

we have enough Petrova dopplegangers

I really don't want to see her, she's just a girl guys fought over, that's not very interesting. Plus if they actually bring her up they should change the name of the show to: Every male on the planet fighting over a character played by Nina Dobrev.

I think we have enough on screen Nina Dobrev. I mean Elena and katherine are fine, we don't need another doppelganger, and with the same family love-triangle story!!!

plz

if they actually bring her up they should change the name of the show to: Every male on the planet fighting over a character played by Nina Dobrev.

^Exactly.

On the end of season 3 or never. Nina Dobrev has done so much.
