I think Spencer ends up convinced that Toby isn't really evil and that he's a double-agent, thus leading her to believe that Mona is behind everything that has gone on recently, which is partially why she attacks Mona. (Just my theory. Not only that, but Spencer hates being second place, so she also has some ill feelings towards Mona due to their constant competing.)
