In the episode, Mary-Kate plays a troubled young woman that Samantha meets while doing community service following an arrest, Access Hollywood has learned.
Sam makes it her mission to help Mary-Kate’s character, which ABC describes as a “bad seed,” regardless of her friend’s multiple warnings otherwise.
Despite her bad girl status in the episode, the actress was all business while filming, according to “Samantha” Executive Producer Don Todd.
“She showed up alone, ready to work, is great on set and is serious about the job,” Todd told People in June. “This is a girl who’s been in front of the camera almost literally her entire life. She’s smart, and she knows what she’s doing.”
