is jujutsu kaisen episode 29 filler?

One year after the mission, the fallout reshapes everything. Gojo has ascended to a level no one can reach, becoming the solitary 'strongest.' Geto spirals in the opposite direction — consuming curses daily while watching non-sorcerers celebrate Riko's death poisons his worldview.

A conversation with Yuki Tsukumo about how to eliminate curses gives him the answer he was dreading: kill every non-sorcerer, and cursed spirits cease to exist. Geto chooses his path.

Gojo chooses his. The two strongest friends walk away from each other forever — until the night Gojo kills Geto on December 24th.
