The gun Hanna was trying to bury is a match for the gun that killed Wilden, and Ashley's prints are all over the bullets. Despite telling her ex-husband that she's innocent and is being set up, Ashley is arrested for Wilden's murder. Hanna faces charges of carrying a concealed weapon and can't tell the police about A because A threatens to bring down both her parents for Wilden's murder. Emily tries to help by leaving the disc of Ashley running down Wilden (and Jenna and Shana helping him up) with Lt. Tanner, but the disc actually contains a video of someone wearing an Emily mask holding a sign with the word "guilty" on it. Meanwhile, Spencer and Toby visit Ravenswood to find Grunwald, but the former housemother isn't talking. Aria must deal with a rumor spreading about her sexual exploits with Ezra, and Mike tries to stand up for his sister finally.
