I hope Kid and Law get PUs from their fight against BM to pose an actual threat to her to some extent, for the PUs, I wish Kidd gets unlock advCoC after seeing BM doing it several times similar to Luffy, but not as good I guess. On the other hand, Law could improve significantly with advCoA or his cursed sword having special ability which he unlocks to multiplies the damage output of his attacks several times either of them or both would be good.
