Hannah asked her how does she know Ethan. Denny said she doesn't and Hannah asked her why she was at his funeral. Denny said that Ethan is her father.

Evelyn tells her about her secret feelings for her best friend and Maddy's boyfriend, Josh Barrett. Denny arranges a girls night with Evelyn and Hannah at the farmhouse and Josh came to the farm to see Evelyn. Denny and Evelyn goes out to dinner at Angelo's one night and sees Josh there, dining with his brother, Andy. Evelyn tells Denny that she really likes Josh, but he doesn't feel the same way. Denny and Chris broke up and she began a relationship with Casey.

A few weeks later, Evelyn was unable to tell Josh how she feels and Denny encourages her to tell Josh about her true feelings. Denny was angry when Andy framed Zac for putting drugs in the shed and tells Casey and tells Hannah to stay out of Andy's problems. Denny was invited to Evelyn's family dinner that Evelyn is organising for Zac and Oscar. Chris asks Denny to dinner as friends and she accepted.

The three races back before Cody, but they were too late and Josh and Evie were kidnapped. Denny fears that Cody will hurt Evie and Josh. With Josh and Evie kidnapped and Andy's still missing, Brax struggles to found out about Cody, but no one from the clan heard about him. Denny and Hannah stays safe with Brax and Casey. The next day, Andy arrives telling that Josh left him a voice message and that he and Evie are held hostage at the farmhouse.
