I expect that producers will elect to revive Dominic IF Danielle is NOT on the block and predicted to go next week. They would want to reunite the two and have two factions with some numbers in the house.If Danielle is voted out and it's her OR Dom, he is still a strong competitor but less golden for them, and the Cassi v. Rachel pairing might also appeal to them, plus they will tell Cassi to up her grooming and dress if she goes back, lol.
Personally I wouldn't have minded seeing the two couple vets make it to the point where they went at it tooth and nail.
CBS likes to return underdogs or pot-stirrers, and they love drama. The newbies are horribly boring so in spite of the barf bag stock getting a big boost from Brenchel, at least the duo gives them footage, fights, and tearfests.
I agree that America's votes are a good source of texting revenue for the sponsor, and that's about all they're good for.
