My sister @BrennaTran and I had a moment this morning after the newest wings video was released. We felt this video threw all of the other theories out the window.
At the moment her and I are rewatching videos and connecting all of the information but we're thinking that this is a case of split personality or dissociative identity disorder (DID). All of the members represent a different personality inside Jin's head. If you would like to be tagged in the card we'll be making later on about this please let me know!!
