For Jin's death, you remember, he loves using the mirror picture, if it's as much a hint as Jungkook's picture (though I hesitate). With the presentation of the House BTS, my thought is to House Army, and Jin who plays, only the characters in withdrawal, including a clock, stuck at 11am for the mini eil and 2min for the big. Coinsing the 12th, if we reverse this is 21. Which would confirm the day of his death.
On top of that, a lot of you are starting to have KPop dreams. And in this RM clip, actually refers, putting the cards in bed. As well as, although some older people already liked before BTS, this has increased, over time. And Jungkook, even if in the story, what in reality is a good action, staying a day, with his family. The other one is what BTS fans are doing now.
