“I'm going to have check the family tree, can I please get one?” Adam said into his microphone.
“I'm going to need a family tree before I continue.”
All jokes aside, Adam later admitted he would like to get to know Cartier better.
“Yeah, she's like a really nice girl. She's really reserved. Completely different. Completely opposite to me,” Adam said in the Beach Hut.
“Cartier might ground me just because like we're so opposite. I don't know. It's only early stages. It's only early days.”
However, Cartier had already expressed interest in Adam earlier in the episode.
“Adam is surprising me every day. His banter has drawn me to him. I love the sense of humour,” the 19-year-old said.
Earlier this week, video footage emerged of the two dining together at a restaurant in May.
While the two weren’t alone, they seemed to be part of the same circle of friends.
