We'd heard that Dr. Anne Sullivan (Annabeth Gish) is returning to Pretty Little Liars, but when can we expect to see the good (or perhaps not-so-good) doctor?

There was a photo of Annabeth Gish on set during the filming of Season 3, Episode 15: “Mona-Mania!” and she's listed as in that episode on IMDB. And now it looks like we can count on her being in Season 3, Episode 18 as well.

When a fan asked showrunner Marlene King, "Will we be seeing Dr. Sullivan again? My theory is that she is Toby's mom," Marlene replied, "#318."

We're excited to see more of Dr. Sullivan. If she's trustworthy, she's a valuable ally for the Liars, because she knows so much about Mona (Janel Parrish). If she's not trustworthy — and this is Rosewood, so who is? — than she could be a formidable enemy. It’s also interesting that Marlene didn’t confirm or deny if Dr. Sullivan is Toby’s mom.

Are you excited for more Dr. Sullivan? Let us know in the comments below.

Catch the next episode of America's Next Top Model Cycle 19: College Edition on Friday, September 7 at 8 p.m. ET/PT on The CW.
