How we cite our quotes:
He trembles, but must investigate as high as he can climb. (16)
Aww, looks like the Man-Moth forgot his jacket. Wait, no, he must be really scared of that climb if he's trembling. No matter—up he goes, because he must.
[...] this time he will manage
to push his small head through that round clean opening
and be forced through, as from a tube, in black scrolls on the light. (19-21)
Each time he comes out, he firmly believes that this time he will make it. He fantasizes about what it will be like once he makes it, and it's going to be glorious.
The Man-Moth always seats himself facing the wrong way (29)
Wrong schmong. This is how the Moth-Man rolls, and he doesn't care about what anyone says. Maybe he's superstitious. It's like wearing the same underwear to all the football games in a season when your team is on a winning streak. Hygiene aside, there's a reason why he does things this way, and he will continue to do them until he accomplishes his goals.
