Headcannon: These two are in the same class and are good friends (It’s possible, Cody was 10 in the Steel Samurai case, and John is 13 in investigations 2, which I think takes place around 3 years later, so the ages match up). Cody likes Steel Samurai, so we know that he likes global studios, so what if after Steel Samurai ended, he started researching the company’s other works, and he stumbled apon and loved Moozilla. Then, he meets John Marsh at school and instantly latches onto him and hangs out with him and talks to him. John is really quiet at first, and he doesn’t really like this random fan boy following him around, but after a while he starts to get used to and becomes friends with Cody. He’s a good listener, and he eventually opens up to Cody about work and life and other things. They become really good friends, and they start sticking up for each other. If a crowd of people start harassing John, who doesn’t really feel comfortable with big crowds of fangirls screaming at him for an autograph, then Cody will start yelling at people and waving his fake sword around until they back off and leave John alone. And John has been shown to be really agressive, he has a bad attitude problem in Investigations 2, so if anyone starts picking on Cody or if they call him names or call him stupid or something, John will get pissed and start yelling at them til they run away.
