PLL boss I. Marlene King broke the news with an Instagram of Mona rocking retro shades alongside Hanna (Ashley Benson).
“Mona’s back, bitches,” she captioned the still. “Happy Pretty Little Liars Day!”
Parrish, 26, also shared a celebratory Instagram.
Mona was missing these past couple weeks while she was “away with her mom,” coping with the trauma of being kidnapped by A (aka Charles?).
Considering the fact that the girls’ torturer isn’t actually Andrew (Brandon W. Jones) and is still at large, the redeemed member of the A-team was probably smart to get the hell out of Rosewood – unlike Hanna, Aria (Lucy Hale), Spencer (Troian Bellisario), Emily (Shay Mitchell) and Alison (Sasha Pieterse), who hustled right back to high school.

So what’s next for the Liars?
“Marlene has been leaving a trail of breadcrumbs, as I understand it, to leave little hints here and there that Charles is around, and that Charles maybe is somebody that we’ve seen before, you just don’t know it yet,” Parrish told PEOPLE after the season 5 finale. “All of that will come to light.”
PLL airs Tuesday at 8 p.m. ET on ABC Family.
