S4, E5: Spencer and Emily make plans to visit a nearby college, but they have very different agendas for their time spent on campus. Spencer's singular focus to figure out Ali's apparent connection to the school contradicts Emily's real fears about her plans for after graduation. And, after a stinging attack by "A," Aria and her brother, Mike (recurring guest star Cody Allen Christian), don't see eye to eye regarding what's best for their parents. Meanwhile, Hanna becomes increasingly frantic when she makes another horrifying discovery among her mom's things, leading her to make a desperate move - with disastrous results.
