What do you think the plot of season 19 will be? I have some ideas.
Since Zero decided to break continuity and take Tucker's sword away from him, I'd like to see Tucker, Wash, Carolina (and the other Reds and Blues if they're up for it) get wrapped up in another story involving the aliens which eventually leads to Tucker getting a new sword.
Another idea: kind of a wildcard option but I had a dream where Caboose had gone full psychotic became the villain, so that would be interesting.
Or just do another anthology season, but with more canon stories. There's still a bunch of characters we haven't seen in a while and events we haven't seen yet.
