Peter realised a moment after he stepped outside that he'd forgotten his bag and ducked back inside, grabbing the first backpack he saw, swinging it onto his back and hurrying back outside.
"I- I guess?" he said. "I- I mean I worry about homework and stuff too." He shifted and rubbed the back of his head with a small smile. "But- If I don't do something then the bad stuff I coulda stopped is on me." And it was something he believed wholeheartedly. He had the power to do something, so he should do something.
He shifted how the bag was sitting on his shoulder and zipped up his hoodie, tugging his sleeves down over his hands and looking once again every bit like the teenager he was. "Are you sure you wanna walk me home? It's-" he wet his lower lip and smothered his wince. "It's not far." If they left now, he'd even get home before May had time to curse him out for being late.
