Yea I def. like Grus. Him being Drake's right hand man was a nice touch. I really just can't wait to see Drake again with him fully leading the SWORD then to see the role Grus will have in it. His DF is damn unique with insane amount of potential when you raise the scale.
We clearly saw he was the dude in-charge after Garp. Then Kujaku after him, so really want to see that dynamic between Drake-Grus-Kujaku.
Since Kid , Denjiro , Jinbe appeared in these last 3 chapters , i hope Neko will appear next . also Drake should help Worst Gen-Samurai-Minks Alliance , in this upcoming raid on 2 Emperor crews and Orochi .....
Hawkins should help too , but he might be still down after Law's attack
I disagree very strongly with the argument that it is bullshit for Sabo to awaken the Mera within a year. Such logic just doesn't apply to OP:
It took Katakuri several years to unlock future sight, but Luffy did it in hours.
It would take Luffy over a decade to awaken his fruits, yet BB may do it (and for multiple fruits at that) in only a couple of years.
