is jujutsu kaisen episode 24 filler?

Yuji and Nobara's battle against the Death Painting brothers reaches its brutal conclusion. Nobara drives nails into her own rotting flesh and uses Resonance to transmit the damage back through the blood connection — turning the brothers' greatest weapon into their cause of death.

The victory costs something: Yuji and Nobara killed beings that were partly human, and the weight of that registers on both of them. Being a sorcerer means making choices that don't feel clean.
