small arms fire and meele blows!
"meele" —> "melee" (unless this is weird European-talk that I'm vastly unfamiliar with)
They all looked up when Scabs entering
This sentence is scrambled, it should be (presumably): "They all looked up when Scabs entered"
“Jabberjabber,” he said with a small nod. Scabs assumed that the name was ironic.
Assumed how? She only just met him so she doesn't know yet that he doesn't talk much. Every other nickname has been pretty literal or accurate (Elbows, Spittlestring, Scabs, etc etc), so why would she now assume this one was ironic?
“Just… Not so accurate now, is it?”
You don't capitalize after an ellipsis.
see for herself the absense of the twin
"absense" —> "absence"
she looked a bit odd and leaning on the table.
"leaning" —> "leaned"
a wide room with thick double-glazed windows revealing a panoramic view of the wastes before and behind them.
Not a crit, just wanted to note that I've always imagined Wheelbarrow to be a heinous mix of an elaborate hamster cage and that thing the Jawas drove around. (Adding, of course, the digger). The windows detail only cemented that. Now that mental image can't be changed.
General thoughts:
This one's a bit of a break from the frankly tense past two, which is a good thing especially given what seems to be coming up. To answer your questions:
1. Yes, I had a good time with it, especially when they were trying to figure out what Jabberjabber was drinking (the true mystery of the series, I pray we learn the answer one day.)
2. No, not at all. In fact, this feels to me like the least intimidating the Olristaan has been yet. But that isn't me trying to decry the writing, you've shown a vulnerable side of her that I actually liked. Having an antagonist be afraid to use the weapon that'll give them the edge but push through that shows a level of dedication to their effort. But I wouldn't describe her a "menacing" in this part.
3. The cliffhanger is almost there, honestly and truly, but I think it could use a bit more build up. Here's what my dumb brain wants from ya: after Scabs sits in the chair with her yummy terracotta brick, let her marinate for a bit, get comfortable. Maybe a little introspection? Just a smidge more? I know she's up to her neck in the stuff and is about to, let me double check this, ah, "eat children," but it's just me spitballing here. The reader gets to ease off more, relax more, maybe let the Olristaan approaching part that just happened slip into the back of their mind a bit more, then get a little more detailed with the "shadow trees" or whatever they are. I'm not saying to explain it all away, but maybe just a bit more? It was a bit confusing to read. Or not, up to you, but at the very least I feel like the cliffhanger needs for cliff for me to run off of before catching myself on the ledge, y'know?
Of course, all of this, especially the stupid stuff after "3." you can ignore as you see fit. I'm no paragon of writing knowledge. If I was, I'd be publishing cookbooks under a pseudonym and living fat on the profit in a cabin in the mountains, protecting my territory from wild animals, like hikers and Mormons, with a twelve gauge from my front porch, sipping sweet tea from a mason jar and gently rocking in a rocking chair all the while.
Anyways.
Keep up the good work, good luck!
