This is an odd paragraph. It seems Taylor hit him twice in the head with no significant damage, which does not make Taylor conclude he's a brute but when he hides behind the refrigerator (meaning any bullet would be significantly slowed down - in fact I'm impressed Taylor's magic was able to accelerate a bullet enough to go through a refrigerator and still cause damage), the fact that those much slower bullets didn't cause any damage means he's a brute? Something here is off.
The fact that the gun seems to actually do more damage later on after he'd gown (and presumably became more armored) is also weird
When she notes that he is a brute is a bit strange and I will have to look into it to make some edits along with some of the other parts you mention here.
For accelerating the bullet to the point of getting through a fridge, I imagine that the barriers made are actually incredibly thin, thus allowing a very large amount of acceleration fields to be layered down throughout the length of the barrel. Skidmark in this story was able to accelerate baseballs to blow up the armoured and minor brute rated head of a lizard demon, so a smaller, and much more penitrative projectile like a bullet would be able to get through a fridge, though in truth, the stopping power would be very small compared to the initial shot in comparison.
As for how much damage Taylor seems to be doing, due to the wall and how she can only really judge the amount of damage done by how the head moves, she can't see that in just a couple of shots she basically shattered the carapace of the side of his head, though I forgot to mention it later, so I will have to go back and add that to her observations before he powers up. For the damage after achieving demon form, the arms are less armoured than his head but after proving that even while powered up her pistol is still denting his armour, he wants to protect his head. Ill have to go over the fight scene in more detail however to make sure it's properly described.
Also I need to go back and properly emphasise where Taylor put bugs on them to demonstrate that despite having wall hacks, she is more seeing where the bugs are and not really details due to how few bugs she has on them.
What exactly stops a demon from burying someone in cement?
Nothing, other than finding the cement or purchasing it to burry them in it. I was more thinking of something quick and out of the way, while also making Skidmark's story of how he and Squealer survived the angels useful, since it took a full month before they finally got dislodged enough to get fished out of the water and be revived.
The contrast between this and the earlier description of their goals makes this sound like sour grapes, if that was deliberate , good job.
Not completely deliberate but not achieving all the objectives can grate on some people, plus, she's trying to see the bright side of things rather than focus on just the failure of stopping a veteran hero and veteran of Hell with an axe to grind with her and her newfound allies gain more power, discover a network of allies she hadn't had access to before, and now might be training a sniper to deal with her and her fellows.
For the Wards I was more refering to events that might have taken place over the time skip but it isn't really obvious so I might have to look it over or elaborate further and specify a specific scenario during the time skip.
