I hope Glasses-kun survives. If nothing else, he's been pretty unpredictable & entertaining with his goofy antics and demeanor.
I'm not sure how Okaya fell down the well in the last panel of the previous chapter but was completely fine AND out of the well in this one. Around 10 chapters ago I saw someone complain that the author is making Okaya way too flawless & invincible to an absurd degree, at the time I somewhat disagreed but now it's pretty tough to think otherwise. It's ok to have the antagonist make a mistake or lose an encounter at some point before the very end.
