Luca's reaction "Oh..." said it all. If he handles this badly, tries to hold onto Gemma too tight, she'll be seriously annoyed. She's told him before she doesn't respond well to possessiveness and it could play right into adams hands.
Jacques is going to lose it isn't he. Small man syndrome coming out against a 6ft 5 Adonis who towers over him who just so happens to be interested 'his girl' - I hope Paige gets a good look at his aggressive side (if "you're fucking pathetic" wasn't enough) and walks. Jacques is a walking red flag for a miserable life
