The Secretary-General, pressed by Avasarala, publicly launches an investigation into the rogue faction — the stroke that finishes Errinwright.
Secretary-General Esteban Sorrento-Gillis — the aging UN leader whose great claim to fame is having been jailed for writing bad poetry — receives Avasarala's high-priority plea to choose sides against the Errinwright cabal. After an agonizing delay, he responds on a public newsfeed, brilliant at looking somber and energetic at once: he announces the immediate formation of an investigative committee into individuals within the UN who took 'unauthorized and possibly illegal steps' with private contractors, invoking his years as a political prisoner and his crusade against corruption. He says nothing concrete, but the act itself is decisive — as Avasarala reads it, if Errinwright had any influence left, the announcement would never have been made.
By moving publicly, Sorrento-Gillis takes Errinwright off the board and throws the UN's legitimacy behind Avasarala's coalition.
