Jay and Chyna have no chemistry. Danica and Josh have no chemistry. Neither of these new pairings have potential.
Davide and Ekin will go back to doing what they did before. Absolutely nothing there that won't end with the show.
Paige and Jacques will get back together. And continue to be a mess. Won't last a day outside even they even make it to the end.
Andrew and Tasha will recouple but still have lingering feelings and be hurt and cry for awhile more. They will probably date in real life after LI but then break up soon or be off and on.
Luca and Gemma are aiming to win and will keep at it. Doubt it will last long outside the villa.
Dami and Indiyah will recouple and the four of them will hang out. They might hook up outside the villa but have never had a genuine romantic connection.
