But while doing so I found it remarkable how fiercely they continued to attack me, even after their mother was already dead. Obviously it was something personal, they wanted revenge. Well, they paid the price.

But it made me think: not all escorts will do their job for personal honour. At least some will be in for the money. After their mother is dead nobody is going to pay them anymore. So wouldn't it be rational for them to break up the fight and leave me alone? I hadn't fired a single shot on any of them up to this point.
I think there should be a probability for escorts to simply flee when their mother dies. When out of range of the fight, they could start to seek for a new employment. Not all escorts, not in all situations, but a probability.
