Well, yeah. The entire climax of the story is missing at AO3. The resolution of the X-File, the reason that Scully shot the parrot, the Tolchuk-induced dream that both Mulder and Scully were having--it's all missing! That's nearly all of chapter 15, in fact.

Thank you for asking the question. I'd have never known otherwise.

It's a much stronger story now that you've read the entirety, don't you think?
