### Summary
Following the shocking reveal of the children's secret mentor, the story shifts back to the aftermath of the attack, but with a humorous twist. The unassuming old sweeper, now confirmed as the maternal grandfather, is provoked by the threat against his family. Instead of a grim counter-attack, he unleashes his fury in a comically overpowered display, casually manipulating a massive body of water to deal with his enemies. The sheer absurdity of the humble caretaker becoming an "angry waterbender" has left readers in stitches, hilariously demonstrating that Gajang isn't the only one in the family with a ridiculously powerful and understated legacy.
