James' life
James Bond wasn't at all jealous of his younger brother, John. James didn't at all want to go to Hogwarts. He didn't want to be a wizard.
Well okay he did, but it didn't matter. He wasn't a wizard. He would never be a wizard. He would rather be a pirate! Being a pirate would be awesome. Much better than being a wizard.
Of course, he never managed to be either of them. Him and John were both well on their way to being secret agents now. If John hadn't got his letter 2 years after their parents died the two of them would have been 100 percent inseparable. You wouldn't have seen James without John, or John without James. If you did you could be sure the other wasn't far behind.
However, when John was at school James could often be seen waving sticks around and waiting expectantly for something to happen, of course nothing did. He wasn't born for magic.
When John graduated, he stayed with James in MI6 until he was 23. After that he decided he would leave. That was when he fell into his cover of John Watson and James pretended his brother had died on their last mission.
M knew that John wasn't dead, so did the Marauders. But other than that no one knew, and those that did were sworn to secrecy, under the unbreakable vow.
