Spencer is NOT happy when she learns that her mother is defending Garrett pro bono and thinks perhaps Melissa is the reason why. The Liars wonder if Melissa had been pregnant with Garrett's baby and not Ian's. Later, Spencer pretends to be Melissa to get her ER records from the night she supposedly lost her baby. She learns that there was no record of Melissa at the hospital that night -- and that Melissa was a resort with their mother instead.
Elsewhere, Hanna seems to be making progress at Radley with Mona. But later, Caleb (unaware that another "A" exists) makes a visit of his own. He tells Mona to stop manipulating Hanna. Mona completely loses it, forcing the hospital to put her on the no visitors list.
Meanwhile, Emily realizes that Ella finished her exam for her and worries that "A" will expose them. Lucas is acting more erratic than ever -- and secretly visiting Mona. And Aria, Spencer, Hanna and Emily confront Jenna about not being blind.
