I agree and think Gemma's savvy enough not to embarrass herself or her family. In the interview Mollie, Jasmine and Charlie said Gemma is as much into Luca as he is in her and all three agreed he's getting a bad edit, said Gemma often instigates fun with Luca but it's not aired.
I haven't watched but apparently the unseen bits demonstrate this. They both come across very differently to how they're being shown on the main show. He's much more fun/chilled out and she's the same.
