March is just a hair too late to reunite with her “child”, as all of Fushi’s vessels are stolen from the Nokker in Kahaku’s arm. When he chops that arm off, it escapes and runs off, leaving a distraught Kahaku, March…and Horse. So what now? March gets on Horsey and rides to find a doctor.
Her path takes her through swarms of Nokkers overruning the city and its defenses, which are now crippled because there’s no Fushi to repair structures or replenish ammo. The three immortal warriors are also out of commission. All hell is breaking loose. But March does manage to attract Bon’s attention. He comes to Booze Man’s house, and is soon follow by Eko, who recovers Fushi in orb form, still attacked to the city.
Bon believes the only way to bring Fushi back is to remind him of the sights, sounds, and smells of the ones he absorbed, since there’s still something of them within him in that orb. He achieves this by stabbing himself, dying, and becoming one of the ghosts that once haunted him. Then he, Gugu, and all the other dead vessels place their ghost hands on the orb, in hopes of bringing him back.
That resurrection can’t come soon enough, as Renril has been all but lost to the relentless Nokkers, who as we know are determined to “free” every person on earth from their physical bodies. A desperate fight outside the hospital ends with Kamu getting smashed by a Nokker ball, then Sera getting arrows in the back from what appear to be Nokker-controlled metal puppets.
Eko, who has a Nokker infecting her arm, spends a good deal of the final third of the episode preparing to leap off the tower (a scene foretold in the OP), but that arm stops her fall, and from it emerges Fushi’s head, this time with those purple eyes Bon bestowed upon him way back when. I am not entirely sure what is going on, but it definitely was a lot, and I can only hope that the fortunes of Fushi, his friends, allies, and the people of Renril will improve when all’s said and done.
