Who is that mystery girl hugging Emily in this photo?! Surprise, it's Rumer Willis!! Actually, Rumer is set to play a new character named Zoe -- and it was initially thought by fans that she'd be a love interest for Ezra. Now that we've seen some significant changes in the storyline for Ezra, we're more on board with the fact that Zoe really is the charity worker who we hear she is. That being said, new PLL photos reveal a meeting with Emily and it can be assumed that they know each other -- thanks to the hug -- but she may have brought some confusing news to the Fields family based on these photos. Some other pics showcase Aria and a mystery man. Maybe it's her brother in that backpack?? We know that it's not Jake because he's photographed in other photos -- just leaning nonchalantly on the brick wall in a very Justin Bieber slash karate inspired wardrobe. Check out those guns! What?! Back to reality, people, he and Aria seem to be all smiles as they chat away. Perhaps he was just waiting for her to arrive and they had planned for the meetup? Just a thought. So this episode is titled 'The Guilty Girl's Handbook' and it airs on Tuesday, July 30 at 8pm eastern pacific..
