Melissa was at the Masquerade Ball: In the previews for the episode, both Spencer and Mrs. Hastings grill Melissa on why she was at the masquerade ball. Melissa is also seen crying and Spencer says, “Why would my sister want to torture us?” So, um, we’re guessing she’s the Black Swan.
Trouble for Haleb: According to the press release, Hanna's (Ashley Benson) desire to visit Mona (Janel Parrish) drives "a wedge" between her and Caleb (Tyler Blackburn), and in this sneak peek they get into a fight about it. We're also promised a "powerful" scene between them — we're not sure if that's the fight, or something else. And, as the press release asks, "would it be so bad if Hanna told Caleb that she needed to see Mona to get information about this 'A?'"
...And Kevin: We'll also meet Kevin, a hipster and coffee shop boss. We assume he is the same boss Emily has in her new job at the coffee shop in this sneak peek.
