I think either Law ending from now as support or he kinda show a new finisher or abilities, with would also proof that he became stronger.
Or he get beaten as the first supernova, because GK was his strongest move and if he don´t have a new finisher, I can´t see him not going down as first. It is like Zoro using Ashura and didn´t do much damage, that is right now Law whole situation. Let see where this going on, but I still hold up the point that Law probably going soon more in support role.
For Kid too, I hope he show more feats.
