Vash successfully contains the blast but at the cost of July being partially vaporized (the crater is later called "July"). He collapses, reverting to human form, missing his left arm (blown off by the energy).
Knives, wounded but alive, retreats with a mysterious figure (later hinted to be a human ally). Wolfwood finds Vash barely alive. Meryl holds Roberto’s body, then stands and takes Roberto’s broken camera – she will continue his work.
Knives activates his own full Plant power, creating a massive energy sphere over July City. Vash tries to contain it but loses control. Wolfwood shoots at Knives to distract him – it fails. Zazie (the giant worm) tries to help but is swatted away.
In a flashback, Rem explains to the twins that Plants are not machines but bio-engineered life forms that feel pain. Knives witnessed humans beating a Plant to force output. This memory solidifies his hatred. In the present, Knives forces Vash to relive this trauma, trying to make him accept that humanity is parasitic.
Final shot: Vash wakes up in a new location, arm replaced with a crude prosthetic. Wolfwood says, “Time to run again, Tongari.” Vash smiles weakly. They ride off on Wolfwood’s motorcycle.
