I love Gemma, to me she is an iceberg cool with real hidden depth. The fact that in such an intense situation she can hold herself so well, she has good boundaries around poor behaviour, she held all of her stuff together with Jacques in spite of the fact that he was bad mouthing her to Luca at the start. She was never even a teeny bit off with Paige over the challenge of having an ex take off in a relationship with a new person in front of her whereas clearly Jacques behaviour shows he was. I think it is incredible that she is only 19 too.
I don’t know about Luca. He is clearly besotted, he is human and so he has flaws and one of his is being possessive. He is funny and I imagine he is good company. I know if I were their age I’d enjoy spending time in his company (although I think I’d prefer Dami).
In all I think Gemma and Luca make a good couple who because of their ages are unlikely to last the test of time but who knows?
