Interesting. I guess it makes sense. Benthic and others from Saws hideout are clearly shown leaving with the main characters of R1 as the walls are crumbing. I don't remember seeing other ships, but it would make sense that they got away as well.
I'm not sure how much that changes the chance that we will see two tubes again in a future movie? But you never know.
I'm still hoping for more reveals on these characters at Celebration. Either as art or toys/collectibles etc.
