Will Bismuth and Steven be on good terms – even become friends – next time she joins the Crystal Gems? Yes, I think so.

To add more weight to this theory, lets go back to the episode in season 1 where Steven/Gems are fighting Lapis to get the ocean back. Those indestructible water Gem clones seem to dissolve the moment Rose's shield makes a loud resonating noise from the impact of clone Steven's attack

As evidenced by both of them saying "Holy smokes!" one after the other near the end of the episode.
