Earlier that day:
As James sat on the train and looked over his shoulder and saw his brother, he was reminded of his first year in which even before he boarded his train everyone wanted to be his friend for one reason and one reason only, his dad. Even the mugleborns knew who he was. Yes everyone in Hogwarts knew who he was, but at the same time they didn't. Sure they knew his name, his birthday, his face and even his favorite color (which was red) but they didn't really know him,not for how he really was. They knew him because of his parents this made the beginning of his first year hard and lonely because although everyone loved him it wasn't real. He would never mention this to Albus but in the first part of his first year the highlight of his day was receiving the letters from his parents. That year James was sent into such a deep state of depression wishing every second that no one knew who his father was. that he was prescribed by a healer to take a diluted version of Elixir to Induce Euphoria. Luckily that all eventually changed when one day when James was on his way to the potions room to take a dose of the elixir he ran into what he thought was air but soon realized it was just David wearing a headless hat a product his uncle George invented. David was a Gryffindor whom though in his year James had never actually talked to because of the fact he was friends with the popular kids, aka everyone who wanted to be James friend. The problem wasn't the fact they wanted to be his friend, but it was because if he actually tried to talk to them they didn't want to hear about his life. All they cared about life of his dad; and because of this kept his distance away from them. But alone without his friends David was different, when he took off the hat and reveled his head he started to talk to James but unlike his friends who would ask things like "is it true your father this and is it true your father that" David said "hi James how are you." Now to an ordinary person this would be meaningless, but to James it meant everything. He now felt a sense of hope and when he showed David his uncles new prototype trick wand (that was basically a real wand but it did exactly the opposite of what you wanted it too) and it was the beginning of their wonderful friendship. but it was no longer just him and David, because one day he and David decided to have a sleepover in the shrieking shack on a full moon (they dared each other). Little did they know a Hufflepuff boy whom they knew his face,didn't know his name because he was so good at blending in that no one noticed him. It turned out that this boy was a werewolf, (James discovered this the hard way and the two boys would end up sleeping in their dorms) But the next day they realized why the face was so familiar, as that same boy was in there potions class and his name was Matt and soon he would became a close friend.
Together the three of them were unstoppable and when his second year came around it was amazing, he even made seeker of the quidditch team which despite the fact it made him seem even more like his father and grandfather (whom he was named after) he didn't care anymore. It was in this year that his cousin Fred joined Gryffindor and he quickly became the forth member of his friends gang. they had great adventures together using the marauders map (he had stolen it from his father) and discovering the secrets of Hogwarts.
Now he was on the train for his third year and he was full of high hopes although a large part of him was worried about how Albus would deal with the gold-diggers, though deep down he knew he would be fine, he always was.
The train jolted and James suddenly noticed that while he was daydreaming the candy cart had already arrived.
