When The Vampire Diaries returns on October 3, there’s going to be a flood of drama because Silas (Paul Wesley) is on the loose and Elena Gilbert (Nina Dobrev) and Caroline Forbes (Candice Accola) are settling in to college. But perhaps the most intriguing aspect of the new season is newcomer Nadia (Olga Fonda).

We will first meet Nadia in the Season 5 premiere “I Know What You Did Last Summer,” when she has a sexy threesome with Matt Donovan (Zach Roerig) and Rebekah Mikaelson (Claire Holt). But what really has us scratching our heads is what she’s going to be doing in Episode 3, “Original Sin.”

In this still from the episode, she’s aiming a gun like she’s ready to shoot. But who’s she aiming at? Well, from the looks of it, she might be aiming at Katherine (also played by Nina). In this photo of Katherine, the humanized vamp looks frazzled and has her hands raised. She looks a little tense and frightened. Perhaps Nadia is gunning for Katherine? We don’t know for sure, but we’re anxious to find out exactly what’s going on!

What do you think is happening? Who is Nadia aiming her gun at? Hit the comments and weigh in!
