Pack your bags, “Bates Motel” fans! Season 3 of the A&E series concluded in May, but it’s almost time to return to the deadly town of White Pine Bay. Stars Nestor Carbonell and Vera Farmiga tweeted from the set, revealing that filming is currently underway for the highly anticipated fourth season. But production on the British Columbia set is not the only thing they’re sharing on social media. The stars have also been teasing a relationship between their characters, Sheriff Romero and Norma Bates.

Fans of “Bates Motel” can’t forget that Romero (Carbonell) and Norma (Farmiga) made great strides in their relationship in Season 3. The two grew close after Romero was forced to stay at the motel after his home was destroyed. However, their friendship continued even after Romero moved out of the motel. Although the two had their differences at times, Romero still killed Bob Paris (Kevin Rahm) in the finale order to protect Norma and her son.

It’s not clear where their relationship will pick up in Season 4, but Farmiga shared a behind-the-scenes photo revealing that the characters will remain close -- at least off screen.

Carbonell retweeted the photo and added his own caption, questioning if the two complicated characters will finally get together this season. “You and your dang questions, Norma … Ufff,” he posted. “Anyone have any Excedrin?”

But while things may be tense between Romero and Norma on-screen, Carbonell and Farmiga appear to be having fun with each other on set. Romero added another photo, calling his co-star’s character “naughty.”

As previously reported, the cast is staying tight lipped on whether or not a relationship between “Normero” will actually happen. Carbonell dished to in early November that Norma is a “frustrating woman,” but wouldn’t say more.

“She’s a tough one,” he said. “She’s a tough nut to crack so we’ll see what happens there.”

“Bates Motel” fans won’t have to wait too much longer. Season 4 will premiere on A&E in spring 2016.
