The "swept under the rug" expression at the end of the chapter kinda made me smile, because it feels a bit like Togashi did that with the arc and the conclusion.
Let's face it, Chimera Ants started horribly (ESPECIALLY if you were reading the first chapters when they were released in Jump, and Togashi was sick, basically letting his 2 years old daughter draw for him). It started to pick up a bit after the first hiatus, what with the Spiders having their moment and the plot starting to make sense again.
But let's face it, Togashi was obviously tired of the story after a while, and the foundations were too shaky to give a satisfactory conclusion. What about, well, basically everyone fucking involved ? Was it really worth it spending all those pages showing us what happened to the lobster-man and the little girl (I don't even remember her in the story) when we have no idea what happened to Knuckle, Gon, and all the others ? What about the remains of the Royal Guard ?
(Or, if you want to be a bitch, what about the second child of the Queen ? What about Leolio and Kurapika saying they were coming as back-up ? Guess everyone forgot about that, but can't really blame it)
It's not a bad thing to give a few details about what happens to secondary characters, but 20 pages dedicated only to 5 of them, especially when they are this non-relevant, feels like a waste, especially after all this hiatus.
Now, I really hope Togashi rushed that because he could not wait to start the next arc, which obviously will be good and please, NOT interrupted every six months again. I have still faith in him, but he really should not mess that one up.
