After Dawn offs Ryan, the PKGs start using their teeth, and Dawn/the PKGs defeat the Pastor, Dawn/Dentata faces off with Brad. It's a relatively brief, verbal face-off between the feminocracy and masculinity, they charge at each other, blackout. Then, Dawn, who won, speechifies for a bit and calls out the infidels in the audience, rallies the PKGs and her manservants, and they all sing together while coming toward the audience (something like "there is a monster..." if I remember correctly). I don't remember anyone chomping on an apple unless I missed it. We don't hear from Brad after the blackout.
The ending's tone worked for me, though I wasn't fully on board with the execution. As things went off the rails more I was hoping for a "Don't Feed the Plants" or "Carrie on a staircase covered in blood after killing everyone" type of mythical horror ending, and this hit the tone I wanted. But Dawn's speech went on a tad longer than it needed to, and the Brad vs. Dawn payoff felt somewhat anticlimactic because I wasn't sold on Brad as a character. I'd also have appreciated a more substantial confrontation between the Pastor and Dawn/the PKGs too. He's such a presence in the show but they just wordlessly kill him off and move on.
