Recapping Season 4, Episode 10 of Pretty Little Liars. Aria goes hunting down a CeCe connection when she\u2019s supposed to be on a Fro-Yo run for Jake, Hanna tries to enlists Wren\u2019s help concerning Mona, and must keep Caleb from spilling all about A to the authorities, Emily begrudgingly accepts an invite to come stay at Mrs. DiLaurentis\u2019s house, and Spencer is still humoring Toby in the plot line about his dead mom who is still dead. At least it eventually leads to a sweet Ali flashback.
