Summary: The best way to get to someone is through the people they love, and "A" knows this better than anyone. Aria, Emily, Hanna and Spencer have had to sacrifice a lot at the gloved hands of "A", especially when it comes to love. Toby continues to pursue Spencer, knowing that she is keeping something from him. With another "accident" possibly popping up at any minute, Spencer is desperate to keep Toby safe and can think of only way to truly end it. Also worried about her relationship, Hanna begs the other girls to stop using Caleb to help with their search. The more involved Caleb gets, the bigger target he becomes. But is the valuable information Caleb is finding more important to the others than Caleb's safety? Meanwhile, Aria is desperate to save her relationship with Ezra still not returning her calls. Will one more "date" with Holden give Aria the opportunity to get the answer from Ezra she is longing for?
