The winter premiere of "Pretty Little Liars" suggested that Mona may be is ready to take down Ezra Fitz. However, we wonder if she knows that her English teacher is "A." It is also possible that she is suspicious of everyone. "Pretty Little Liars" executive producer Joseph Dougherty talked to E! Online about this particular subject.

Mona is suspicious about Ezra's motives. However, it is not known that to what extent she is suspecting.

"I think Mona thinks they're both working for the same person, but of course that might be ego on her part," said Joseph Dougherty.

"So again I'm not so sure she thinks she's working for him. Being a super genius and being an evil genius is rough, it takes a lot out of you," added Joseph.

Mona knows that something is not right about Ezra, but has not arrived to the point that confirms that she knows about his ulterior motives. She is not aware of the ugly "A" game.

It will be exciting to watch that how long Mona takes to find out that Ezra is up to something and hiding secrets from the town, Liars and student. Will Mona figure this out before Spencer, Aria, Hanna and Emily?

Meanwhile, in "Pretty Little Liars" season 4 episode 15, "Love ShAck, Baby," Travis and Hanna meet over coffee and the former informs the latter on the news.

"Apparently, someone saw her at a train station in Maryland. By the time the cops showed, she was gone."

Travis also informs that someone made a huge deposit into CeCe's accounts.

"They think someone paid her to kill Wilden?" enquires Hanna.

"Lots of people wanted him dead," replies Travis.

"Pretty Little Liars" season 4 episode 15, "Love ShAck, Baby," airs January 14, 2014 on ABC Family.
