Hollyโs hunt for Sonia Matthewsโ killer is over. Sheโs face-to-face with the person who ordered the hit. But the killer isnโt going down without a fight. Will Holly end up taking a bullet?
Last weekโs episode of Human Error ended with Holly (Leeanna Walsman) stumbling across a body. In this weekโs season finale, Holly, Jarred (Rahel Romahn) and Gabe (Ethan Lwin) examine the murder scene, trying to work out who killed the victim and why.

The team discover a key to a safe box, which leads them to a remote address. Finally, everything is starting to make sense. But then Holly gets a call. Someone she cares about has been abducted by the killer.
โSheโs like, โWeโve got to get everyone onto this and itโs got to happen immediately,โโ Leeanna, 44, tells TV WEEK. โThatโs when you see Holly really ramp up.โ
After putting pressure on Allan (Gyton Grantley), the hitman who gunned down Sonia (Kate Angus), Holly gets the information she needs. The team race down to the waterfront. Shots are fired, and the killer tries to escape on a boat. Holly is determined to stop that from happening.
โShe just keeps going and she puts her life at risk,โ Leeanna says.
Will Holly and her unborn baby be okay?

Meanwhile, Dylan (Stephen Peacocke), whoโs the best friend of Hollyโs husband Luke (Matt Day) and the father of her unborn baby, is still holding out hope that Holly will want to start a new family with him.
โHe knows that in pursuing this heโs putting an end to a friendship with Luke,โ Stephen tells TV WEEK. โLukeโs been there to help him with the grieving of his own wife, so itโs huge for Dylan. But he pursues it anyway.โ
Is there any chance of Dylan and Holly ending up together?
