'Pretty Little Liars' season 6 spoilers: Does Jason hold the clue to Charles' identity in episode 3?

Wikipedia

The first two episodes of "Pretty Little Liars" season 6 were already shown, but fans still have no idea who Charles is. Will the third episode finally give some light on the identity of the Liars' most dangerous tormentor? 

In the promo trailer for the episode titled "Songs of Experience," Spencer (Troian Bellisario) tells her half-brother Jason (Drew Van Acker) that when she and the girls were still detained in the dollhouse, she saw the name "Charles DiLaurentis" in one of the rooms. 

It seems like the name rings a bell for Jason, and his other half-sister Ali (Sasha Pieterse) tells Spencer and the other Liars that Jason always told her that something seems missing in their family. Does Jason have a brief memory that he used to have a twin brother? 

Before the end of the trailer, Spencer announces to the girls that Jason finally told her who Charles is. Is Jason telling the truth, or he is just tricking Spencer to cover up for someone? 

The official synopsis for Pretty Little Liars season 6 episode 3 states:

The girls' lives have been turned upside down by their captivity and each one of them is looking for answers to make sense of their ordeal. Aria (Lucy Hale) focuses on Andrew (Brandon W. Jones) by trying to figure out who this boy really is while Emily (Shay Mitchell) tries to connect with a new friend. In true Spencer fashion, she is on a mission to get answers about Charles from Ali and Jason. Hanna (Ashley Benson) wants to bring the four friends back together so they can move past what happened in the Dollhouse."

The third episode might also feature Sara Harvey (Dre Davis), the other girl discovered captive inside the dollhouse. She could be Emily's new friend based on the synopsis. Can she help the girls pinpoint who Charles is since she was hidden in his lair longer? 

"Pretty Little Liars" season 6 episode 3 airs Tuesday, June 16, on ABC Family.
