Luckily for fans of the Queen of Mean, Mike Montgomery (Cody Christian) may have a few secrets that could exonerate Shay Mitchell's character.

"I think it's a little overdue, but Mike has got some secrets that he hasn't shared, and the nature of his relationship with Mona and some of the private secrets they shared together are going to be pretty key to what people are going to see in the next 12 weeks," writer Joseph Doughtery ("Through a Glass, Darkly," "No One Here Can Love or Understand Me") teased, according to People.

It is unknown if Mike is privy to Mona's current resting place, but that will be one mystery that is solved before the end of season 5.

"There certainly is a trail that leads to remains," Daughtery told People. "And that will happen in the winter season."
