Since Lisa’s death, Jasper is unable to face police work while Dan’s throwing himself into long hours at work. With Adelaide travelling the world, her sister Zelda (an old flame of the Dean’s) arrives to look after her home. Maiya hires a new DC, Chloe Highsmith, and with Dan, they tackle a tricky case involving the disappearance of a young woman on a boat. Jasper is forced to get involved too.

Jasper is dragged to a retirement home by Zelda to meet her date, Peter, when a murder takes place at the home. Jasper is drawn into the case but Dan finds this frustrating and ends up snapping at Jasper. Maiya insists the men have a therapy session together where Helena helps them to open up and they manage to solve the case together. Meanwhile, the Dean is put out when he learns of Zelda’s date.

When a school inspector is found murdered in his home with a number of items stolen, the team assume it's linked to the local burglaries going on and know they need to catch the culprit. Ms. Snares spots similarities between Jasper and the Dean and starts to wonder if they're related, and Helena finds herself ruffled when she learns Jasper is getting additional help in the form of drum therapy.

When an actress is stabbed on stage and the director’s daughter is also attacked, the team jump to investigate but Chloe gets herself into trouble by overstepping her mark with the daughter. Helena also knows the family involved in the case, so Jasper reaches out to her for help and we see Helena open up to Jasper about her personal life. The Dean and Zelda share a moment but the Dean pulls away.

Adelaide’s painting is vandalized and the gallery owner is killed; but Jasper is distracted from the case after learning about Ms. Snares’ DNA test. Jasper agonizes over opening the results. In light of the news, the men come together and the Dean tells Jasper about his feelings for Zelda. The Dean races to stop her getting engaged and proposes himself.

In the lead-up to Zelda’s wedding, Jasper is wrestling with his feelings for Helena. Dan becomes obsessed by a dying man’s final words, but Maiya worries it’s about Dan’s grief over Lisa. Zelda has doubts about the wedding but Jasper’s advice makes him realize his feelings for Helena. Ms. Snares takes Jasper to Collins’ lecture on the warrior gene and Jasper is intrigued by something he says.
