Credit: Photo via Facebook Photo: Actress Juliana Harkavy on The Walking Dead Set

Last week we told you that Dolphin Tale actress Juliana Harkavy would soon be making her debut on The Walking Dead Season 4. Juliana’s exact role hasn’t been confirmed quite yet, but thanks to a tweet from fellow TWD newbie Alanna Masterson (Tara Chambler), we know that Juliana will make her grand debut of the AMC drama this Sunday, November 24, in Season 4, Episode 7: “Dead Weight.”

When a Twitter follower shared a picture of Alanna (as Tara) and another woman she thought was Juliana, Alanna kindly corrected the mix-up. “That’s actually Audrey. Juliana next week!!!” she wrote back on November 18. (Audrey is of course Audrey Marie Anderson, the actress who plays Alanna’s on-screen sister, Lilly Chambler.) The photo the fan shared was one from the November 17 episode, a week before Juliana is scheduled to show up in the TWD universe.

On November 11, Juliana posted on Facebook: "I am currently [lying] down and alive, but two weeks from now I will join #TheWalkingDead. Set them TiVos!"

So who is the New York native playing, and for how long will she be around?

We don’t really know anything about Juliana’s on-screen counterpart yet, but if you take a close look at the sneak peek below, you can spot someone who looks an awful lot like Juliana standing around Martinez after he pulls Meghan from the walker ditch.

As you know by now it’s impossible to predict how long anyone will be on this show, but a photo Juliana shared back in September of herself posing with Norman Reedus (Daryl Dixon) and Andrew Lincoln (Rick Grimes) could suggest that she has some interaction with Team Prison.

Are you excited about Juliana’s character, or do you need to know more about her first? Vote below!

The Walking Dead airs Sunday nights at 9 p.m. ET on AMC.
