Grandma Carter and her Chinese and Russian counterparts killed a lot of Rogue AIs at Singapore. Their strike teams and the AIs that fought with them breached Singapore’s defenses and helped destroy the entire nest. Burned it all the way down to the silicon. Then they partied like warriors who had gone through hell together and walked out the other side. Not a one of them wanted to fight the others, and they made certain to report that fact to their superiors. And their superiors were quick to report how helpful all their counterparts had been in saving the world to their superiors back home. Grandma really just wanted to go home. She’d gotten way too close to dying more times than she could count with her boots on, and she wanted peace. She got it.
