In the afterlife, James Potter watched as his son was being gossiped about and tormented by his fellow classmates and was reminded of his own time at Hogwarts, when he behaved rather immaturely. Of course, what he had done was not motivated by a discriminatory ideology, but he still felt that his own son had behaved much better in childhood than he himself had. He often wished he could tell Harry how proud he was.
Being a Marauder, of course, James was also very proud of Harry for continuing the tradition of going on adventures and breaking the rules. He watched as Harry met Draco for the first time and was impressed that his son had immediately recognized Draco’s views as incorrect. He was even more impressed that Harry had met his school rival even before school began. James hadn’t met Severus until their train ride to Hogwarts on 1 September 1971.
