The case itself was a given whom the killer was, I liked how they used the song, " Almost Paradise," at the beginning. As for Lilly the drama again starts, as soon as she walked into her father's house and sees her sister there. The two later meet up, and a photo is shared; that will be important during the next episode. Christina's storyline isn't about to go away, anytime soon leading us into the next episode.
If the case was stronger I would have enjoyed it better, but it was too clear who the killer was. Also the fact that they didn't add more to Lilly's father talking to her in person. I always enjoy it better when someone tells her something in person.
