Hanners is taking that WAY better then I would in her shoes. The sword would be out, Gordon would be a dead anthroPC spider hallucination.
Hanners is comfortable with her hallucinations. She gives them names and knits them sweaters. She just doesn't like to talk to them in public. Peer pressure.
I found Hanners' reaction entirely rational.
When I started perceiving my body changing sex, after living as a woman-pretending-to-be-a-man-because-I-looked-like-one for decades, my initial reaction was to seek a good psychiatrist, of course. It was obvious I'd cracked under the strain. No other explanation possible. Humans don't change sex like that - or so I thought.
It took me a long time, with many patient people explaining that they saw it too, before I accepted even the possibility that I wasn't hallucinating. It was only when my GP started sending me the completely crazy blood test results for hormone levels that I started accepting that my imagination just wasn't up to the job. Either I really was completely detached from reality, imagining
everything I perceived, or the Universe was stranger than I imagined. When I found other cases, mostly FtoM but at least actual examples that proved that some humans
did change sex naturally... I had to re-assess. The hypothesis that I was crackers still seemed the most likely, but was no longer the only alternative.
The point is, I know exactly what it's like seeing something you know (mistakenly) cannot be true. In my case, seeing, feeling, touching, smelling... and examining in detail, to try to see if it was my mind filling in a pattern, as we all do when something enters the "blind spot" in the eye.
You know you're hallucinating, so you try to do what a sane person would do. Nothing rash. Try to get help. My Panic reaction, emotions in deep-freeze.
I'd do exactly what Hanners did. It's only rational.
