Some clues from the promos

• Toby and Spencer will be reunited at long last - and how will they share this moment? Their first time perhaps? But will it be all happiness and love? Or is there darker things to come for Spoby?
• Looks like Spencer, being Spencer will confront Paige once and for all - but what does this earring signify about Paige? Her being the betrAyer and the member of the "A" team seems slightly too obvious, so we're putting our money on Paige not being the ultimate betrAyer, although there is a massive amount of questions and suspicion surrounding her still - could she be Maya's killer?
• And how could things get any worse for the Liars?
• Finally, Mona is back on our screens - she looks like she's leaving Radley, but dressed up as a matron at Radley - could she fool the workers and escape Radley? Or will she be released? And why is back in her "A" hoodie? Back to check on the "A" team and her minions? Is she the "A" we'll hear speak? Or someone else?
• What role will Caleb play in the finale? Will he be as determined as the Liars in the search for answers as to who is Maya's killer and who is "A"? And what lengths will he go to to do so? Or could he be the member of the "A" team that will be revealed?
• But why are the Liars standing over a grave? Is it Ali's or Maya's? And have they created a ploy to lure "A" to this spot, and is this how a member of the "A" team will be revealed?
• Nate looks pretty menancing in the promo - but what role will he play? Threaten to kill Maya's killer when they are revealed once and for all? Or will he insist on him and Em being together? Will we see his previously shown violent side come out once again? Or could he be Maya's killer?
• Shocked faces all around for Ezra, but we're guessing this is at the sight of seeing Maggie again after seven years - but will Maggie reveal Aria's visit to her class, Ezra's child, Dianne's possible involvement and what does this mean for Ezria?
• And Garrett is also back! In a suit and smiling? Will he walk away from his trial a free man on the streets of Rosewood? We think so!
• Where is Emily? She looks like she's away from the Liars, in a secluded spot - but we don't recognise the place? And looks like she's in danger of getting hurt - but we reckon she'll get out safe enough, but why did "A" lead her to this place, to just let her get away?
