if i had a time machine

Lawrence promised Adam he would come back, but he never did. Lawrence was a liar, and he wanted revenge to a extreme extent. He had been playing along with Jigsaw, or John Kramer, plotting his revenge. He was fetching some things for John one day, until he was lead into a creepy shop with a old creepy dude running it. The man asks Lawrence ''what would you do if given another chance'', and not knowing what the fuck he means; he was blasted into the past... literally.
