Celina Juarez (Lisseth Chavez) is no longer a rookie, and after completing her training, she's ready to take on the streets solo. The Rookie Season 7, Episode 13, "Three Billboards," makes her first solo ride an affair to remember when she's pinned down in a dangerous situation without any backup. "When anti-LAPD billboards emerge throughout the city, the team searches for who’s responsible. Meanwhile, a car bombing prompts an investigation, Miles (Deric Augustine) reconnects with an old friend, and John (Nathan Fillion) and Bailey (Jenna Dewan) assess their ability to adopt," reads the logline for the episode airing on April 8, teasing the various arcs to be tackled. ABC also released a sneak peek of the episode, previewing Nolan and Bailey's attempt to adopt and Celina's rough first day.

Now that Bailey's ex-husband is not dedicating his life to ending hers, she and her husband, Nolan, can breathe a sigh of relief.
