So Chapter 51...
-Moro is running around the galaxy absorbing planet after planet, and growing exponentially more powerful.
-Vegeta has gone to Yardrat in hopes that its inhabitants can teach him brand new techniques that might help against Moro. I doubt one of those techniques will be IT, but we'll see.
-Merus is ridiculously skilled/powerful. He was casually evading attacks from SSJ3 Goku without really exerting himself at all. Goku powered up to SSG against him, but their training location couldn't take the output, so their sparring match was stopped.
-Goku believes Merus is a far superior fighter, to the point that he actually wants Merus to train him. Why? Because Goku thinks Merus can help him fully master UI:
So it would seem that we may very well see Goku activate UI again in this arc, which is not at all what I expected... mmm
