BigHit's IPO and Bang's billions that he just made in one day depend on BTS and BTS depends on their robotic "clean" image, meaning no personal life, statement, relationships. An eternal parasocial connection/relation with a group of mostly underage girls called army.So what does this mean?
In order to ensure the investors that this scenario will stay like this, back then I've estimated what now became reality, that their shares and enforced lock on their wealth with the company will be part of the "warranty". If one of the members falls out of the line, especially the younger ones, they will practically loose all their money.
If they would have valued their freedom more than a stadium full of minors and playback on stage, they would have rejected the deal, because now they stand to loose everything if one does something stupid (in Bang's eye). Maybe Jin or some others got a better deal, but most of them don't really matter to the fans. The game is always focused on Jungkook, Jimin and especially Taehyung.
As far as your screenshots are concerned, I do not quite understand what is your question.
I don't believe in any secret signs or message BTS is trying to send. Freemasons always try to put all their "symbols" in everything as sign of their own worship and loyalty. It often makes no sense. The purpose is to throw them out.
BTS has no input or influence over lyrics, songs, videos (often they have no idea about what video is going to be released for their song), booklet, photocards (they were wandering around visiting their own shop looking at pictures as if they've seen it for the first time, because they were unaware about what the bosses have decided).
I don't believe in "sacrifices" at least when it comes to BTS, so far Jin was "programmed" to die a few times over the years, he is still alive and BTS are at this stage more valuable as a whole, than whatever "rituals" of "sacrifice" one wants to believe in.
If Taehyung can't stand Jin, it could be as always because of Jungkook with whom Jin seemed to have always been touchy. Probably the same reason why he seems uncomfortable with Jimin, maybe he feels that someone took his "BFF" away, which is a very childish way of thinking. He seems to be more easy going with the rest, because the rest didn't interact much with Jungkook.
Taehyung changing his behavior or becoming more distant - my opinion is that he tried a different fake attitude in order to get the member's attention and also - every other member around him evolved, matured, focused on something, but this is again the same old theme with Taehyung I end up writing about.
I don't think members intentionally leave him out of something, there is always the element of jealousy, but everyone else has something in their life they work for, while he refuses to work.
Maybe deep down he feels weird about the situation, but nobody is stopping him doing something on his own.
His ups and downs point out to some bi-polar condition, he takes medicine (he is obviously on anti - depressants/anxiety meds, he has the typical swollen cheeks and eyes), drinks.
Rest assured BigHit has hundreds of people working for them who each come up with one idea and they put all together, which is why everything related to BTS - every story, video, entry, is overloaded with millions of little things, to keep fans preoccupied in "analyzing" what it could all mean. The more they analyze and share on twitter/social media, the more engagement, the more money are being earned.
Of course, as part of the Freemasonry, they will bring in everything, including their b21 line, masonic symbols, characters, satanic meanings. The same things you will find in every other project from any other band of other companies.
The difference between BigHit and the rest is that they were unable to bring up another band so they\re focusing on BTS and put all their masonic symbols and creatures in their stories, games, toys.
They tried with other bands and failed, so now, their only golden ticket is BTS, which is why their IPO is actually a real danger, more than any "ritual" or "hint", "secret message" etc.
