The pair continue to row in the fallout from yesterday's lie detector test.
In tonight's show, in the aftermath, Jack vents in the Beach Hut: “Imagine you keep saying something to somebody and they’re telling you you’re wrong and you’re lying. Just giving me the hump. What is the point? Just going around in circles.
"I’ve said ‘mate, you’ve got nothing to worry about.’ My head isn’t going to be turned, I’m not going to be tempted on the outside by any girls at all. It’s not going to happen. All I’m getting back is ‘oh no, you will.’ What do you want me to say then? ‘Oh yeah, I will be.’ I don’t understand it.”
Dani meanwhile seeks counsel with Laura and Alexandra as she cools off from her earlier clash with Jack: “Obviously with Jack, ever since I’ve been in here, you know, it hasn’t been easy the stuff I’ve always heard from the outside.
"His past, the girl that he was with was in here, she explained how he was to her and it was awful for me, it was not the Jack I knew. I completely get that I probably have changed Jack…everyone wants to be that girl.
"I want to be that girl when I get out of here, and have all that. I don’t want my boyfriend’s head to be turned. Does any girl?”
Expressing her fears for their future together, she bluntly informs the girls: “I can’t be with a liar.”
Elaborating further on the upset caused by the outcome of Jack’s lie detector, Dani tells the Beach Hut: “I’m just so upset with him right now. I just think I’ve never had to walk away from a situation but he wasn’t listening to a word I had to say.
"He was just being so defensive of it all. I just want him to understand where I’m coming from. I’m p***** off with him and I never am. I’m just hurt, I am hurt with Jack.”
With Alex doing his best to lend Jack a shoulder to cry on, Jack refuses to back down and insists Dani is in the wrong: "Do you know what mate, I’m just really upset and angry at how that went and I’ll tell you for why. She’s upset like ‘could you be tempted by other girls outside of here?’
"All I can do is say to her ‘Dan, you’ve got nothing to worry about, let me show you.’ Which is what I kept saying. But she wasn’t having any of it. Do you know the thing that’s upset me the most right? She’s upset and having a go at me for something that hasn’t even happened yet.”
Aware of Dani’s ongoing insecurity that Jack’s head will be turned on the outside, Jack insists: “The only way I can set that straight is when we leave, I can’t change it in here.”
With the tension still palpable as the Islanders head to bed for the evening, Jack and Dani once again clash in bed together.
Jack snaps: “You’re doing the worst thing you could possibly do by saying ‘don’t be with me then.”
Dani replies: “Obviously because you’re upsetting me, you keep making me feel like it’s my fault.”
Jack reacts: “You went about it wrong, I’m sorry, and then you stormed off, I’ve never stormed off from you.”
Dani say: “Maybe you deserve better then.”
Jack comments: “That is the most dramatic thing I’ve ever heard.”
Dani concludes: "Go away.”
The following morning, Dani reflects on the terrace with the other girls: “It was just really horrible last night with Jack. We didn’t (cuddle) at all. It’s weird. We always cuddle and kiss. I don’t want to row with him. I just want to sort it out with him today.”
Acknowledging her own faults in the fall out, Dani talks to the Beach Hut and declares she is ready to speak to Jack and work through this latest obstacle.
She says: “I just want him to understand why I was upset, just have a little bit of understanding towards me. I am a bit stubborn sometimes and I don’t like being in the wrong. I hate saying ‘sorry’, it’s such a struggle for me.
"I do want to have a chat with him and see where we can move forward with it because it’ll just get a bit petty otherwise.”
When the couple finally come face to face, says: “I understand why you were upset about being tempted outside. I understand why you were a bit upset about that. But I haven’t actually done anything.”
Dani responds: “I know you haven’t, I never said you had done anything though. It just upset me the whole situation why that one come up, I couldn’t understand why. Why you’d be unfaithful on the outside?
"Because me and you have been so good in here that when that question came up of course I’m going to think ‘what?’ Of all the questions, I don’t care about any of the other ones. That one is so important to me.”
Desperate to offer Dani some reassurance, Jack insists that Dani is worrying about nothing: “The only thing I can say to you is that when we leave, you’ll see that you have nothing to worry about, you really have got nothing to worry about.
"But essentially, I love you, want to be with you, and I want to have a family. That’s what I want out of us two and I’m so happy that I’ve found it.”
