Pretty Little Liars producer Marlene King revealed via Twitter that Mona Vanderwaal (Janel Parrish) did "all but two things to the little liars," so if you're thinking the person in red who visited Mona in the psych ward is actually the mastermind behind Mona’s actions, then you may want to think again. (Nevermind that Marlene King repeatedly states that Mona is the “A.”)

Mona told the mystery visitor that she "did everything she wanted her to do," leading us to believe she was working for someone else, but if Marlene is telling the truth (can we trust anyone these days?), then it's more likely that the visitor was just a partner-in-crime, not an “A” head honcho.

So who visited Mona in her new home away from home, aka the looney bin?

- Alison DiLaurentis's (Sasha Pieterse) suspected twin
- Melissa Hastings (Torrey DeVitto), aka the possible Black Swan
- Jenna Marshall (Tammin Sursok), who wants revenge on the little liars
- Someone totally unexpected
