Glitch/Hooks

Video Games: Video games are the lens through which Glitch experiences the world. People familiar with them will find him much easier to relate to.

Digital Souls: Glitch doesn't meet many Lost like him. Beyond just video games, any other Lost associated with electronics, computers, and other more recent technology will catch his notice.

Breaking Stuff: Glitch is not a subtle person. He is good at breaking people, places, and things. If you want to do something loud, dangerous, and flagrantly destructive, he is your guy.
