Jay is definitely playing a game. All these stories coming out as well about his recently dumped girlfriends. I don't know why he thinks he'd be a good match for Paige. She seems very giggly and outgoing and the complete antithesis to his personality we've seen so far.
I get the vibe off Jay he's the kind of guy who'd take offence at you refusing to go home with him after a first date and send you horrible texts saying he never fancied you anyway and you're a fat, ugly prude anyway. He clearly thinks a lot of himself.
I can see this going one of two ways; Jay moves on to Antigone very quickly and Ekin Su will then try to push back onto Davide, get rejected and be dumped from the island and Danica will be saved. Or Davide will click with Antigone despite Jays best efforts and Danica will be dumped. I don't think Jay would risk swapping out Ekin Su for Danica.
I really like Paige. She's a stunning girl and she seems fun and bubbly. I think she needs somebody like Jacques in terms of banter and energy, I'm just not sure if Jacques is the right Jacques for her. I hope he proves me wrong though!
