Gender gets assigned randomly. “Him” shouldn’t be there, that’s my mistake.
As for the grammar.txt, it’s in the source files. I guess you could find it in the “network” tab of inspect element? Let me know if you still need help.
For me it came from https://v6p9d9t4.ssl.hwcdn.net/html/1106973/0.6/grammar.txt, not sure whether it'll move around over time or not
