Apologies if any of this comes off as rude. I may have let myself get a bit too sarcastic for some lines.
I'm out of ways to explain it that I didn't used already, on the last two pages (20 and 21) of comments. If there's no good enough explanation, I don't know how to make a better one.
You seem to be confused about what "unreliable narrator" means. You're saying that TCGM should have done a better job explaining how Taylor is tougher than Alexandria.
No. I'm talking about you as narrator. Who, in my opinion, failed to shown Taylor's thoughts in believable way here.
The issue is that
TCGM is not the narrator;
Taylor is. TCGM may be the *author*, but the story is not written from TCGM's perspective. Much like in Worm itself, what we see of the world is colored by Taylor's perspective. That is what 'unreliable narrator' means. The narrator (again, different from author) is not omnicient, and as such not everything in-story is going to be perfectly accurate, because the narrator might not know better. That's what TCGM meant by "taylor can't read the wiki". That Taylor,
the person whose perspective we are reading, does not have an omniscient perspective. She has to work with what she knows, not what TCGM knows. Or do you think that everyone in-story should magically be able to know everything about people... in which case, why has nobody arrested Thomas Calvert for being Coil?
ARE YOU COMPLETELY NUTS?! SMOKING CRACK? HIGH ON SOMETHING ELSE IF NOT?
... No, really? Taylor Hebert, the girl who killed Alexandria, warlord of Brockton Bay, she who slew Scion, the Queen of Escalation? Being "arrogant, sure of her own conclusions, and doesn't consider half of what she should."? (this is ripped straight from the quote that you were questioning)
You seem to forget that, in canon, we get shown that one of Taylor's core traits is her sheer determination. The first time she meets Armsmaster, she chooses to infiltrate the Undersiders, despite Armsy,
one of her childhood heroes, telling her it's a bad idea. That's at the beginning of the story, where she'd had even more time under the Trio than here.
So personally? I'd say her being cockily sure of herself after gaining the powers of a small starship are pretty reasonable. She is literally more of a heavyweight than literally anything on the planet with exception of the Endbringers and Scion. I'd say that considering that a starship compressed into human size could rival Alexandria for durability might not be that unreasonable... Especially when said ship's computer system is now sharing her mind, thus tinting her view of things.
Also, that was a bit rude, which was completely unnecessary
