Yeah I feel you bro - the choice to hide Gaban’s interaction with Sanji is telling. Gaban clearly said something, the issue is how would he know Sanji has the power of love, could he sense it with his observation Haki. However there are points against it: One, Gaban, who claims to be a ‘missionary of love’, did not say anything about himself using the power of love to damage the holy knights; two, how would the power of love work?
