John is depressed after the fall, and a few years passed by when tried to commit suicide. Afterwards, he is in a coma in the hospital, when he dreams about being with Sherlock. Everything is sweet and going swell. Throughout this, the one person who refuses to let him go is Sherlock, who is alive and sitting in the chair by his bedside, not letting go of his hand. John wakes up eventually, and sees Sherlock sitting there, and is in shock for obvious reasons.
Is anyone interested in being my John?
