Mackey calls you back to school because PC Principal has informed him there are.
While still inside your house, you have the opportunity to become familiar with the controls as well. The Talk 2: The Gendering is a main mission and part of the walkthrough for South Park: The Fractured But Whole. I was wondering if anyone knows weather that changes if I go back to mr Mackey and change my character to being a cis female. Keep this in mind for the rest of the game and loot approach everything colored yellow. Granted you'd think after you've picked which gender you are/identify as they'd tell the teachers of your classes which in turn would mean the whole school(via rumor/classmates) would know your character's gender/gender identity. In another reddit post i read that regardless of what gender you pick they call you a him, but in that post the people who choose female also said they get a lot of remarks like 'hello little miss' and Cartman telling you have really pretty hair for a guy and such. The game made a few jabs at being trans so I know they acknowledge the fact that my character is that but after that everyone still called me him instead of her. The New Kid is able to freely explore South Park, interacting with characters, undertaking quests, and accessing new areas by progressing through the main story.
I'm a few hours into The Fractured But Whole now, as gender I filled in 'female' and 'trans' because thats what I am.
