In the abandoned barn, we hear "Spencer's" voice saying "Hanna". Hanna wakes up to see a younger "Spencer" who tells her that she has this and that she'll be okay. "Spencer" promises Hanna that she won't let her die in there, prompting Hanna to say that this is a dream and that she can't help her. Spencer tells her that a dream is an experience and that an experience is real. A distraught Hanna says that she should have listened to "Spencer" and that maybe it's a good thing that they don't know who killed Charlotte because she would tell if she did. "Spencer" tells her that she can escape and that she'll always be there for her. It is later revealed that Hanna was speaking to Spencer's twin Alex Drake.
In the seventh season premiere, it’s life or death for one of the PLLs. After Hanna’s kidnapping by “Uber A,” the PLLs and company desperately race against the clock to save one of their own — but the only way to do this is by handing over evidence of Charlotte’s real murderer to “A.D.” In order to do so, the girls must decide what lines they are willing to cross, lines they have never breached before, because once they cross that line, there is no turning back. #PLL #PrettyLittleLiars #SaveHanna
