Shannon is going to lose it When...
Tamra and Vicki have their annual makeup.
I'd say there is a 95% cancer all three Vicki, Tamra, and Shannon will return to the show. When that happens, Tamra and her newfound faith will forgive Vicki for all of the stuff she has done. Tamra's new bestie will get even crazier than she already is when the Vicki and Tamra inevitably reunite.
Shannon also won't have her friend Heather or her (kind of) friend Meghan to turn to as they are both leaving the show. I won't be surprised if production straggly casts new new/brings back Housewives that are much more likely to be "team Vicki" than "Team Shannon" to make this the "Shannon gets it" season.
