- In Grillo-Marxuach's self-produced show Ask Javi, you can ask him any question and he will try to answer it. However, as a question that everyone kept asking was "What is the Monster?", he finally addressed this as best as he could.

- Attended high school in Ann Arbor, Michigan, home of the University of Michigan.
- Suggested in his July 9th Ask Javi podcast that Damon Lindelof is Speaker from The Lost Experience.
- Offers a forum for players of The Lost Experience to post their opinions and questions (answered as he sees fit) on his LiveJournal.
- States through the Notes from the Experience LiveJournal that he is not Speaker (although he is taking over Speaker's former blog), but he has "been known to essay the role of a certain donut-lovin' deejay on occasion."
