This man's mind

Trapped in his own mind, John led the rebellion against his own body. And all Sherlock could do was watch and wait, as that man's mind fought for survival. How he loved that man's mind. I've seen a lot of fics where Sherlock loses his memory, etc, but I always wondered; What if John were the one who lost himself? Will have two endings, one Johnlock ending, and one platonic ending
