While I'm fine with the shows ending, I'm considering this as a form of canon to the series. This was to well done! Great work.

This is good. But how come in this story when jack killed aka in the past Ashi didn’t sees to exist?

Okay no. The mine name is...ending.
made me scream into a pillow. loved all the rest of it. I thought it was funny how Jack 'idly' wondered why the tower/cave thing blew up.
