Pretty Little Liars - Spencer Asks A Nerd About The Phone Number - "Gamma Zeta Die!" (4x05)

Meanwhile, Spencer asks a student at an information desk about the phone number. He says he doesn’t know who the number belongs to since it is unlisted. After some snarky banter, he tells Spencer it probably originates on Greek Row, a street on campus, since the first few digits match other phone numbers from that street. 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, 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. #PLL #PrettyLittleLiars
