Killua will eventually find out about the death of gotoh. Canary didn't want Killua to find out, thus the magical beast transformed so Killua will never find out. But he will find out eventually that gotoh died by the hands of hisoka. Meaning there will be a battle between Killua and hisoka.
Who do you think will win? If rage was able to make Gon defeat pitou, the same might happen to Killua ( but without him transforming)
