“We had a blast creating this character with Mischa,” says executive producer Bert V. Royal of Barton’s Olivia, a patient from another rehab center who strikes up a friendship with Vern (Daniel Franzese), another resident of the show’s central recovery house, Springtime Meadows.

In a case of art imitating life, the former Marisa Cooper from The O.C. famously revealed in a 2013 People magazine story that she had been court-ordered into rehab after her 2007 DUI, followed by a 2009 stay in a psych ward for what she called “a  full-on meltdown.” Now healthy, it sounds like Barton’s first-hand experiences helped inform her colorful Recovery role. “She saw the ridiculousness of the character, yet still managed to make her seem real and likable,” continues Royal’s fellow executive producer Karen DiConcetto. “She’s a really clever and lovely actress.”

“No, I have no idea what Seth and Summer are up to these days.”

Recovery Road premieres Monday, Jan. 25 at 9/8c, on Freeform; Barton’s episode is slated for February 15.
