For the longest time, he's been stuck, frozen, held in place by fear and confusion. As the fire consumes, as it tears and rips away the puppet, the cage of confusion just falls away. Leaving only new panic in its wake.
The last he'd been in the outside world, he'd been alive, he'd been breathing. The security guard promised him he'd be okay. It'll be alright they promised. Lies. It wasn't. He died. He died and got stuck. Years spent watching the kids around him. Hearing that song, that same damn song over and over. Screaming, shouting, desperate, afraid, but no one ever heard. No one ever came. All this time, only ever just him.
The fire doesn't touch him as he walks among the flames. He's long left this plane, he's beyond the fire's reach now. There's a sick satisfaction as he watches this cursed restaurant burn around him. It brings him no peace though, not even as he finds the Bonnie suit that has haunted his living nightmare these last years. It's giving out an unholy scream, screeching to the heavens but nobody up there better be listening.
Instinct guides him to take the monster's hand in his own, seeing horrific hellish images flash through its mind as he sees what it fears in this moment, what it thinks is waiting for it. He smirks, letting it go. Burn! Burn you monster! Hell awaits!
The day shift guard is a short way away, passed out, face down amongst the flames. He's not the same one from before, instead he's new, clearly unwell. A touch of his arm fills the spirit's mind with far worse images than those from Afton's mind. Though even in amongst the nightmares, the madman is grinning, laughing and giggling.
This man is innocent, at least in these walls. Let the monster fall but let the man live, allow him to walk free. Give him the chance to die another day. Instinct, reflexes. If he was to think too hard, he wouldn't be able to do it, but without the focus, he pulls the guard from the fire, and watches as the fire trucks try to contain the blaze.
That old place that's never been up to code. They'll never win. In a few hours, the sun will rise, and Fazbear's pizza will hopefully be dead for the last time.
And from the ashes, Natemare will rise.
