'YOU NEVER WALK ALONE EXPLAINED'
In ‘I Need U’ Jin in is in a deeply dream where he can see all members. All of them represents his alter egos or emotions. All of them are happy and having good times but nothing last forever.
In ‘RUN’ we can see how Jin is acting weird, he’s starting notice that nothing is real.
In ‘AWAKE’ (the short film) he awakes, while he’s walking in the place where he is we can see some stuff that appears in the other short films. He made that stuff to feel them in real life, to not to feel alone. It was not enough so, he dreams again to see them.
In ‘BS&T’ the scene when V cover the eyes of Jin is because he knew that Jin was going to leave them but he doesn’t want that to happen so basically he killed him. He made Jin to sleep forever to be with them.
In 'Spring Days’ all looks a little sad and lonely. They were on streets but why no one appears except for them? Because they are not real. Also they visited places that appears in another MVs to say goodbye to that moments that Jin made.
And there we are, the train scene. They were heading to heaven, also Jimin hangs tennis in a tree(just a pair). When someone does that it means that someone has passed away, Jin died and the others too because they were in the imagination of Jin. Also the solo of Jin (AWAKE) makes references to the sky, you need to pay attention at the lyrics by now.
The meaning of 'You Never Walk Alone’ (and from the other eras too) is that even if someone leaves you is not forever, they will be always with you walking and supporting you by your side. Enjoy the little moments in your life with that persons before they leave.
