Back to the Bay reports that on Tuesday, Tori’s budding romance with Duncan continues to be mired by his previous relationship. Meanwhile, she and her brothers fight to save Decker, who holds the key to their past.

Seven Network posted a sneak peek of the Sept. 20 episode. In the trailer, the police arrived at Decker’s niece house to investigate on the kidnapping incident. At the hospital, Tori tells Brody that things aren’t looking good for Decker. Meanwhile, Spike brings Hope to the hospital and tries to administer injection on him. Justin panics when he learns about this and tries to Decker’s room. Elsewhere, Caroline tries to kiss Duncan, but he pulls away. Refusing to give up on him, she tells Tori to stay away from Duncan and give him a chance to be with his family.

“Home and Away” recap

In the previous episode, Evie lashed at Mason after he admitted he’s falling for her. She said she liked things the way they were, and Mason’s admission ruined it. Later, Evie told Matt about what Mason said. Matt explained to Mason that Evie cannot handle a relationship right now – all she needs is fun after everything she’s gone through. Mason told Evie that he regretted what he said and he’s fine with their arrangements. He also claimed he was lying about falling for her.

Justin headed to the address that Decker gave – it looked like an abandoned house. Justin knocked on the door, but there was no answer. He tried to look for a way in, but a woman suddenly appeared and attempted to hit him. She tried to run away, but Ash and Kat – who arrived minutes after Justin – caught her. Justin told her about Decker and his car accident. It turned out that the woman, Hope, was Decker’s niece. She asked to speak to Justin in private, and he explained everything that happened. He wondered why Decker sent him there, but Hope said she doesn’t know anything.

Justin headed out to talk to Kat and Ash as Decker’s niece and her younger sister packed their things. Suddenly, they heard a scream from the house. When they rushed to see what’s happening, a couple of men were trying to take the two girls by force. Spike was inside the car. The perpetrators managed to grab Hope, but her sister Raffy was saved by Kat. At the hospital, Brody was ecstatic when Decker showed some movement. However, he suddenly went to shock, but not before muttering, “Spare her.”
