I would say that the climax of the story was in previous chapters. So this one was not really anti-climatic, but rather a resolution where things are wrapped up.
I believe my seventh grade English teacher would refer to it as a denoumet. Except she would spell a lot better.

By the way, for experiments, if Red or anyone wants to mention Doctor Da Costa, or I could, I was thinking of a simple one, where a person comes to be interviewed and while they are sitting waiting for him to come in, an assistant sets off a couple of firecrackers in a room behind them. So that the person is startled, but otherwise would not be hurt. The study would be to see if they are affected, how long they remembered it, and so on. Some troll groups would not have the firecrackers, and the study could look at ball players and other athletes like the president, soldiers, and others of both races.
I'm not sure if Doctor Dacosta performed experiments like that or not, but it would be interesting
