Well it appears that Jade had been challenged by a fellow villager and in this village there are a few kinds of challenges which have different outcome for both winner and loser and this challenge is a vore kind so the loser must be eaten. Even if the winner doesn’t want to. And Jade rather not have to eat her but if she doesn’t she will be devoured as well, so she has to do what must be done.
Looks like jade’s jaw is a little sore after eating just a large prey, mainly because she doesn’t really eat people. I don’t know if she needs more practice or not, but why did that other cat want to fight Jade in the first place?
