In my mind, spirits generally have some super far out expiration date (otherwise, Spirit World would be fucking packed lol) and that any excess/outside strain just speeds the process along. In the grand picture, Botan isn't fading away anytime soon but still, most spirits don't face mortality but Botan has been around it enough in recent events, it's enough to shake anyone. Now she's getting attached to her life as a temp. human. Almost dying should rattle anyone who isn't a psycho. XD I think her almost dying could even jog part of her previous human life before she did die. That is just food for thought though. I'd rather the internal struggle come out slowly than all at once.

I think in terms of Kurama saving Botan as we have planned, we considered either a knife or a fall but those two have been done, we could try a third option, maybe something with chemicals or drowning? I don't think Yoko would be needed but in the future maybe without so many people around (like fighting a badass demon like Goshikuro) then Yoko is def. going to make a cameo for Botan's sake. That'd be fun.

And I should be on for another 1.5-2 hours. ^^
