Evil Morty

S6 seems to be setting Prime up to be the overall big bad of Rick and Morty, but with Evil Morty being confirmed to return in S7 and S8, I wonder if this will be the case. In the case that Evil Morty remains a villain, there's several possibilities. 1) He becomes a separate threat from Prime for the rest of the shows run, being as dangerous as he's always been while allowing Prime to retain the big bad status. 2) He teams up with Prime to kill our Rick and Morty to advance his own agenda and to get revenge on the "main" Rick for creating the Central Finite Curve and ends up sharing the main villain status with Prime. 3) Rick Prime dies, either at his hands or that of our main duo, in S7 or S8 and Evil Morty cements himself as the main villain for the rest of the series and the true-final-boss of the show. Which scenario do you think/prefer to happen?
