Hi mods! I wanted to ask about missions and suitability.

While Jon is ten and I don't plan on putting him on missions that are extremely violent or have a high chance of death, he is a superhero (of sorts) and has seen a lot of stuff. Not to mention fought off his fair share of robots and dinosaurs, etc. I don't plan on letting him tackle on anything on his own, but is it possible, with the right person/CR, he can be allowed to take part?
