Pretty Little Liars - Jason Watches Mona's Death/Jason's Alibi - "Through a Glass, Darkly" (5x14)

At the police station, Tanner, Jason and Toby are watching the footage obtained from when Mona was murdered. Tanner tells Jason that there were three cameras hidden in the house but only this one had relevant footage. She also informs him that the batteries in the cameras ran out months ago, they were working on Thanksgiving. Mona’s attacker's face cannot be seen, but the attacker’s blond hair is visible. Tanner questions Jason whether he can identify the attacker and he admits that the blond girl in the footage could be Alison and confesses that he lied earlier and that Alison wasn’t at home at the time that Mona was killed. Three months have passed, and Mona’s friends and family are still mourning their loss and more adamant than ever that Alison had something to do with Mona’s death. Ready to put “A’s” game to an end and get justice for Mona, the PLLs ramp up their search for evidence that could prove Alison killed Mona. But with Alison claiming her innocence and having a seemingly airtight alibi, the Liars may have to resort to more shady tactics to put Ali away. Meanwhile, Emily and Paige reach a crossroads in their relationship, and Aria starts to worry about her future. #PLL #PrettyLittleLiars #NoEscApe
