The pair have been reunited after the second villa twist and both stayed loyal to one another.
“I’ve missed you so much,” Jack tells Dani in tonight's show.
“Honestly, I’ve missed you madly,” she tells him, “I didn’t think I’d miss you this much.”
Jack tells her: “It’s made me realise my feelings for you… All I wanted to do is ask if you were okay.”
In the Beach Hut, Jack says: “Being back in the villa tonight and being back with Dani, I feel absolutely over the moon. I feel overwhelmed with it. I feel so happy. This feels so nice.”
However it's not all worked out for the pair, with Jack's ex Ellie Jones joining the show. She was picked by Sam Bird to return to the main villa.
Dani talks about Jack’s ex, Ellie, being with Jack in the second villa: “You having an ex in there. It isn’t nice. It’s not that I don’t trust you because I do completely. When the came through, initially I thought ‘Oh, he’s had feelings for this girl, he possibly might miss me and then she might somehow worm her way in.’ I haven’t got a problem with her.”
Jack tells her: “What me and you have got is better than anything that I had with her… I promise you, I’ve never felt like this before. I haven’t. I mean that.”
“I felt like I’d lost my best mate in here as well,” Dani says.
In the Beach Hut, Dani is glowing: “I haven’t felt this happy since he left. It’s made me realise he is my bundle of joy. I love being around him. He’s proved me wrong, I genuinely thought he was going to upset me and he’s made me even happier.”
Later in the Beach Hut, Dani talks about adjusting to life living with her boyfriends’ ex: “Exes are exes but to actually live with them and be around them and not be able to avoid them, it is a difficult situation. I will just have to deal with it as a woman and not a girl.”
In bed later that night, Dani and Jack tell each other they are the best boyfriend and girlfriend each other has ever had.
Jack clearly has something he wants to get off his chest.
“I actually feel like I love you a little bit. I’m in love with you,” he tells her.
“I do feel I love you,” she tells him back.
“I do actually love you. I do love you. Do you love me as well?” he asks her.
“Of course I love you,” she tells him.
