I agree with the hundreds of posts in regard to the lack of comprehension on the part of the poor Moab LE chaps.. They did miss the trick , though, by ignoring the speeding, and the original headsup from the public re Brian's propensity to batter women in the main street in broad daylight.... but....
In my opinion... Brian has been doing this all his life.. He was in a state of utter relaxation after bringing Gabby into line, she's a sobbing wreck, her morning ruined, her aspirations denigrated, her psyche shattered , and now, he has an opportunity to actually bring down a heavier oppression on her, what a moment for him, hence his casual stroll out of the car to begin his instant method of deflection.
She's crazy, I'm long suffering. She has silly aspirations, while I try and manage the fall out. She needs a bit of a talking to, while I must have some blokey understanding.... and so on.
And he is good at it. Long years of practice, probably on every human being he ever came in contact with has been subjected to Brian's peculiar gaslighting tactics, with always the very same result, Brian coming out of whatever nonsense he got up to , as clean as a whistle. That is the goal. This is what LE needs training in, the smooth operative who is instantly cool in circumstances that he should be a tad rattled in.
If he has to diminish Gabby, or whomsoever, that is what happens.
I don't think Gabby lasted long after that restaurant episode. .. ( interesting to me was that it was all women wait staff, Brian's favorite , ) and his four goes at claiming the high ground gives a bit of an insight into how far he liked to go. Because he liked to push things to the limit.
Gabby going back in to apologise would have been seen as the ultimate betrayal by Brian, ( no clue as to civil discourse at all ) and she would have shamed him, and he would not, could not live with that , under any circumstances.
Is he dead?... He isn't in that swamp, alive.
He isn't an attractive man, she could have done so much better...
