We have another promo (promo #1) and three all new sneak peek videos into Pretty Little Liars episode 20, "Someone To Watch Over Me":
Emily is thrown when Sean comes to her asking about Paige. He assumes it's because she's Hanna's friend - not because of her own history with Paige.
Hanna shows the girls a photo of an owl pendant she found in Caleb's things. She assumes it's a gift for her, as a memento of their first night together.
Spencer laments to Emily about her current troubles with math - but she really means her life in general. Then things get worse.
