This is right after his harsh boarding school teacher inexplicably becomes a slathering sycophant of wonder and mystery and begged to see Big Foot. And then the kid is like, "adults can't see him, they don't believe in anything...but if you truly believe...then it doesn't matter if you're an adult". and then SWHOOM, red light bathes the window and they look out and there he is, Big Foot, standing out in the foggy red, looking at his disciples.
