Feeling frustrated with the pace at which the Traveler storyline is moving (or not moving) on The Vampire Diaries? Well, you’re not the only one! TV Guide talked to executive producer Caroline Dries about the mysteriously nefarious sect of witches and when their storyline will come to fruition.

"What we've been trying to do with The Travelers is keep this undercurrent of danger through the whole season, but not quite explain what they're doing because — shocker! — it will impact all the characters in a negative way," Caroline said. "[Near the end] of this season they'll make their agenda known and their leader will come forth."

The leader she’s talking about? We’re pretty sure its Markos, a dark-yet-charismatic leader from a faraway land. Though he hasn’t officially been connected with the Travelers, from the hints that the Travelers storyline is going to start picking up some steam, we’re guessing the respective big bad forces are one-in-the-same. Handsome newcomer Raffi Barsoumian has been cast to play the part, and we’re super excited about it.

When will the Travelers begin to show their true colors? Well, Markos is set to make his first appearance in Season 5, Episode 18, but we know that Bonnie will be discovering an unsettling plot against her friends even sooner than that. According to the synopsis for Season 5, Episode 15, “Bonnie learns of a terrifying secret that will threaten the lives of all her friends.” Might it be Travelers-related? Sounds pretty negative to us!

What do you think the Travelers are up to? Are you bored with their mysteriousness? Sound off in the comments below!

Catch the next episode of The Vampire Diaries on Thursday, March 6 at 8 p.m. ET on the CW.
