I was the slave, not the master
The Creature reverts to the terms of his last confrontation of Victor
Frankenstein, when he called Victor his slave and demanded his obedience
(3.3.3 and note). The effect of this recantation, however, is
not so much the simple reversal the diction connotes, as an erasure of the
polarizing of his terms. Both he and Victor were slaves, mastered alike
by their antagonism.
