According to Leo's ending, Mr. Kliesen could still be alive. He is said to have gone missing on a journey when Leo was still a child, but his daughter vowed to be just like him.
- Mr. Kliesen seems to be based on Indiana Jones. Both wear Fedoras, wield pistols and bullwhips and are seen running from boulders, referencing a similiar event in Raiders of The Lost Ark, which was the first movie that Harrison Ford starred as Indiana Jones.
