Let the Water Hold Me Down
Pretty Little Liars Season 2 Episode 16 (01/16/12)
Lucas still hasn't returned home, although he has spoken to his parents a few times. His absence makes Hanna nervous and frightened that Lucas will come back to confront her. Her preoccupation with Lucas leads to fights with both Mona and Caleb. Eventually, Lucas shows up at Hanna's house to explain what happened. Lucas was terrified to tell Hanna that he stole Caleb's money and lost it betting on a basketball tournament, and he's been selling his collectibles to repay Hanna's boyfriend.
Meanwhile, Spencer finds a bunch of cell phones and a receipt from a newsstand in Philadelphia in the attic of the lake house. She visits Philadelphia and finds the Rehabilitation Center Jenna attended when she was blinded. After speaking to a former friend of Jenna's, Spencer steals the sign-in book to show the girls that Garrett came to visit Jenna the night Allison disappeared, and the two signed out that evening but never returned.
