At The Brew, a worker opens the locked door for Mona. Mona tells the guy to lock the door, as she believes someone is following her. Mona is shocked that no one has turned up for her call, and asks where everybody is. Lucas arrives and tells Mona that they are not coming, as Alison has gotten to them and have gone back to calling her "crazy Mona". Mona looks on defeated before looking into the mirror and asking Lucas whether a person can be crazy and not know it. Lucas tells her that if she starts to believe this, Alison wins — however, Mona states that she is talking about Alison and that she has gone "full on socio".
With Alison leading them down a dangerous path and “A” barring them from telling the police the truth, Aria, Emily, Hanna and Spencer feel trapped and are desperate to find a way out of this mess by joining forces with Mona, resulting in an aching loss. Meanwhile, Alison begins to build up her own army now that the PLLs have turned their back on her and Spencer ends up in the cross-hairs of Bethany Young's murder investigation. #PLL #PrettyLittleLiars #FAtalFinale
