Good ones. At the time I read "Guy was convinced he was ninety-seven years old and had died and gone back in time to his younger self via train station." as being a shoutout to several other time-travel based fan fiction stories like Harry Potter and the Nightmares of Futures Past, Oh God Not Again!, Backward with Purpose, and His Own Man; but it could equally well be hinting at a time traveler or two working behind the scenes in this story.

Honestly, there have been so many time travel based stories that I really hope this doesn't turn into another one.
