Julie's comment about a change in the game means someone's coming back.They sure gave Cassi a big build up and spent no time on Shelly because they knew Cassi was going and wanted to give America someone to root for.
Also, the Adam/Dom spotlight...wondering if that foreshadows them being on the block with one of them going only to have one voted back in. (Dom)
Otherwise, I think Lawon is vulnerable. Jeff made a negative comment about him last episode IIRC. There is not much choice for Rach unless she wants to screw her vet alliance. I hope Bren talks her out of that.
BB will have them talk it for the cameras so they can show it on the show, though. Just like JeJO did about potentially booting Brenchel. That was all BS.
