5. Ghosts
The dead will be with him, always.
She, in particular, will prevent him from being lonely, even while she keeps him alone.
He will drift through life, after there's no mission left, no battles to fight, no wrongs to right. He will watch as he slides into middle age, and welcome the day when he realizes he has passed the halfway marker.
His bones will grow fragile like teacups, and his vision, never keen, will dim until he no longer sees that which is, only seeing that which was once and will once again be.
As he drifted through life, so will he drift into death late in his ninety-first year. When it happens, she will be there to welcome him home.
