We know from previews that Mona will be released from Radley Sanitarium and back attending Rosewood High in the Season 3B premiere (Season 3, Episode 14: “She’s Better Now”, airing January 8). That’s sure to rile up the Liars, but Brendan Robinson tells TVLine that her return will impact “everybody involved with this whole situation, including Lucas.”
“We’re going to learn a little bit more about Lucas’ relationship with Mona,” says Brendan. He adds that Lucas will be making “some kind of confession. But I can’t say to who, or how or what it involves.”
