I don't know this group all the way and I haven't seen a whole lot of their videos but I have studied Jk, by accident. It sort of turned into a puzzle I wanted to solve.
In watching the videos, I quickly got the notion "What is wrong with Jk"? He seemed so out of it. I went through different thoughts about what was going on. The things that entered my mind were that he was bi-polar, autistic, abused, hypnotized. I felt sorry for him. I felt he was the most talented out of the group and was being forced to stay.
As I looked more and more I noticed during televised/recorded interviews Jk would be either very fidgety or zombie like. Then I noticed his eyes always looked into a camera as if getting signals from someone through the camera. I came to find that someone was Tae. I was like wtf. Tae is Jk handler! These were videos from like 2017-18. Then I saw the others doing subtle hand and eye signals and I thought "they're ALL in on it", "he must be a loose cannon and they have to do stuff to force him to stay". I feel he is all in now and don't get controlled as much. (I liked looking at award shows because BH doesn't control what's shown and a lot of them are fan cams.
So then I looked at videos of them at award shows and ALL OF THEM were giving signals to each other AND other groups around them were giving signals too. When they were on stage, the Hosts would also give signals, I thought "what is really going on here, what are all these secret signals about". I feel whatever it is, it is much bigger than BTS.
