I imagine she navigated those things with great difficulty and made the best decisions she could. She, like any other person with a medical condition or disability, exists in a world that usually will be hostile to her survival. Yet she must still exist within it. Sometimes people have to do things like take flights and rarely can someone afford to take measures that would best protect them (like a private flight or something in this case). Sounds like she didn’t want to announce her private medical information to everyone around her so she did what she could to keep safe, buy all the peanuts. Ideally she wouldn’t have to, peanut allergies are pretty well known and if we cared about increasing access for people not having peanuts for sale on planes is a pretty simple step. Until then people will keep being put into scenarios like this then scrutinized for the choices they make.
I tried a few mentioned here and settled on Artemis for kbin and Megalodon for Mastodon for now.
