Blood on the Tracks 15

Having finally found himself free to end it all, Seiichi is pulled back from the brink by a telephone call from the police: "We have your mother in protective custody."

Facing Seiko for the first time in twenty years, Seiichi finds an old woman who neither recognizes him nor seems to fully recognize herself. And yet, during their strange reunion, her memories return.
Seiichi's rage erupts, but he cannot bring himself to strike the woman who plagued his thoughts all these years.

And later, the feelings in his heart draw him inexorably back to her side...

Thus begins their long, long night together—and Seiichi gets his first glimpse into the true source of the darkness within his mother.
