The pair have a heart to heart - which begins with Dani in tears.
She is upset about their decision to nominate Alex and Samira in last night's vote.
She cries: “It just upsets me. I feel like we really made the wrong decision. Compatibility doesn’t mean romantically all the time.
"I don’t know, now I’m looking at things I just feel like I’m horrible. I can’t even look at Samira, I can’t even look at her. I just hate it. I just feel bad. I feel awful.”
“I’m glad I’ve got you,” Dani tells him.
“I’m so glad I’ve got you,” he says, “I feel really lucky that we’ve met each other. I really like you, I do."
“I feel exactly the same,” she smiles. “You are my best mate."
“I do eventually want to go out with you,” Jack admits.
“Well you hold that little question until you’re ready alright babe,” she laughs.
In the Beach Hut, Dani opens up: “He is like my best friend and I feel so lucky to have someone like Jack. My whole life I’ve waited for something and I feel like Jack is that person now.”
The next day, Jack and Dani are having a cuddle.
“I reckon you’re going to be my girlfriend one day. Do you?” Jack says.
“We’ll have to see if you ask me… You’d ask me in here?” she asks.
“I’d like to be real…” Jack starts.
“Would you? You’re funny,” Dani laughs.
“I could see it could you?” he asks her.
“Yes,” she tells him, “It’s weird though isn’t it?”
In the Beach Hut, Jack comes over all bashful: “I hope I haven’t scared her off saying that. It just come to me when I was laying there I just thought of it, I thought I’d love that. I just say how I feel and it just comes out like verbal diarrhoea! Why do I do this? I’m such a melt mate!”
