On leaving the main building of Aether Paradise, we are confronted with the sight of Hau and Gladion with a bunch of Skull Grunts. In the short time it took me to experiment to see if the front door was open, Gladion has knocked out two Skull Grunts. Impressive, considering Gladion has not yet formally defected from Team Skull.
He then barrels down this long path to get to the guy at the other end to his own theme. The Skull Grunt closest to the other end, that guy on the left, shrugs as he goes by, the only one to be on screen long enough to emote.
Yeah, I don't think that formal resignation is going to be required.
