The Vampire Diaries Nadia (Olga Fonda) is still one big question mark. What does she plan to do with Katherine? Does she know her boyfriend, Gregor, is threatening Matt’s soft, sensitive palms? And what exactly is a Traveler? Olga dished to E! Online about her mysterious on-screen counterpart — but what did she have to say?

"At this point we're not really sure what her powers are. They say that she is a traveler but then she did say ‘I don't really travel, I kind of do my own thing,'" said Olga. "I think we get to know exactly who she is and what she is in upcoming episodes. She's still a mystery at this point."

It sounds like Olga knows quite a bit more than she’s letting on, which we can respect — as long as her character reveals (and powers) are epicly awesome.

According to the synopsis for this week’s episode (Season 5, Episode 5: “Monster’s Ball”), Nadia will be revealing “her surprising history” to Katherine, so hopefully those aforementioned answers will be coming sooner rather than later.

We are especially itching to learn more about the Travelers. Not only are Nadia and her Matt-possessing boyfriend part of the gang, but Silas and Qetsiyah pledged allegiance back in the day. Who are the Travelers? What do they want? And what is up with that knife Gregor coerced Matt into protecting? The future of Matt’s formerly unblemished palms depend on these answers!

What do you think is up with Nadia? And who are the Travelers? Share your theories in the comments below!
