“But she’s got a warrior’s skills: hyperawareness, hypervigilance, adrenaline-sharp quick-scanning for danger, for triggers.”
– a categorical claim that describer Brannan’s constant condition. She’s got skills that are not normal for an ordinary person in her surrounding. This claim makes you assume that her skills come from the PTSD, but there’s no proof for it. These symptoms could be caused by hard work and tiredness, because she gets just about 5 hours of sleep and she’s busy all the time and has no time to rest.
“She was recently standing behind a sweet old lady counting out change when she suddenly became so furious her ears literally started ringing”.
There are a lot of people out there that just were raised to be spoiled and inpatient, they act the same way and they have no PTSD on their clinical record. Reader is being manipulated and forced to feel compassion for the sweet old lady. First of all, elderly people are most likely to be helpless and suffer from a memory slips and feebleness. For those reasons, many people have sympathy to the older people, especially if they are sweet, even though Brannan most likely doesn’t know that lady, so it’s just assumed by author to get to the reader’s feelings.
“Her nose starts running she’s so pissed, and there she is standing in a CVS, snotty and deaf with rage, like some kind of maniac, because a tiny elderly woman needs an extra minute”.
This kind of impatience is most likely exaggerated with expressions and comparisons. Yes, she turns into a furious woman, but nothing happens, she keeps her emotions inside. The descriptions conflict with the warrior’s skills – being pissed, snotty and deaf with rage has nothing to do with it just because of an old lady, unless she provides any potential danger. One more characteristic is being added to the elderly lady description -she’s tiny and old and sweet, so she looks even more helpless comparing to the “kind of maniac”, pissed, healthy middle aged woman.
“Brannan Vines has never been to war, but her husband, Caleb, was sent to Iraq twice, where he served in the infantry as a designated marksman.”
The statement about Brannan seems to be unnecessary, it’s the second time it appears and there are other ways of starting this sentence, if author wanted to talk just about Brannan’s husband. However, she makes a connection between the woman’s mental problems, and her husband being to war at some point of his life.
