Why did Jessica trust Victoria Dallon to convince a bunch of volatile kids (whom she met in group therapy!!!!) to not form a hero team. Is she stupid
This is actually a common misconception.
You see, Doctor Jessica "child strangler" Yamada had been wanting to kill these teenagers with attitude for some time, but she had a conundrum!
She only had 2 hands!!!
But you know who has many hands?? A miss Victoria "hippity hoppity fuck your property" Dallon!
The entire interaction is Jessica trying to subtly signal to Victoria that she wants these teenage dirtbags eliminated. That's why she's so pissed when she returns and finds out that Victoria failed to kill a single child!
It's all in the subtext, but I wouldn't expect the below par average reader on this website to understand this. You need a very high IQ to understand Wildbow Web Serials after all.
Fun little math trick I find really helpful: the ratio of a mile to a kilometer is within 1% of the Golden Ratio. That means that if you have a good memory for Fibonacci numbers (1 2 3 5 8 13 21 34 55 89) you can convert pretty accurately by taking consecutive Fibonacci numbers.
For example, 89 kilometers is really close to 55 miles (55.3). Or, say you need to convert 26 miles to kilometers: 26 can be written as 21 plus 5, so taking the next Fibonacci number up gives 34 and 8, meaning it should be around 42 kilometers. Sure enough, it's 41.8 km!
