Yes, it's the obvious title. So sue me.
I was having a think in the shower this morning (as you do), and had a thought pop into my head. It was kind of a cool thought. It led to a couple other cool thoughts. They suggest a character for a story, but I'm not quite sure yet what the story would be. I'm also pretty sure I don't have the chops to write either character.
The subject: Time travel. But not as you know it.
