How is the reveal of Mona being "A" going to affect Toby?

Keegan Allen: Now it’s just raised a lot more questions and everybody is a lot more paranoid as to how it slipped under everybody’s noses that Mona was “A” this entire time. So I feel like it just might make Toby a little bit more weary, pressing for answers, possibly going out of his way to find out more information, because he did go and find out from Dr. Sullivan because they were keeping him in the dark. Now I guess it’s affected him in the way where he just wants to know more and find out why he was kept out of this for so long.
