Suppose Harry chooses to take the train at King's Cross Station and once again witness and participate in his life as another person.
If you take the train and go forward, you will not necessarily die, and you can come back again. I think Harry didn't go back immediately to kill those who were OOC, so be careful!
There are mostly stream-of-consciousness psychological descriptions. Harry may not be mentally healthy at a certain stage, so be cautious.
Chaos and crazy imagination, the inspiration comes from the "To the Moon" series and the "inner child" theory of psychology.
Purpose: Self-reconciliation
