Yes, by rights, Amber and Jordan should have been dumped after Casa Amour, all the other singles were. They're only left in to purposely cause strife. Amber will couple with Ovie on a friendship basis at the next recoupling, Maura with Curtis, leaving Marvin dumped.
Molly and Tommy have a clear run at winning, it won't last on the outside though, I give it the standard 6 month contractually fulfilling 'relationship' at the most.
I can see it lasting for a while if they dont do the whole spin-off/magazine shoots/presenting duo thing that others have done. They should take pointers from Camilla and Jamie, rather than Kem/Amber, Jack/Dani and just take it slowly.
