"I'm just here to take the pictures." That's sort of Peter Blotting's tagline. Whatever the event, birthday parties, Gringotts break in, mass ghost 'protest floats', Peter was there with a camera on hand.
When Elvira left him and took the kids, she suggested that he write an autobiography Life of Peter Blotting: I'm just here to take the Pictures. Peter thought that was a little unfair. He was a little absent minded, sure, but his pictures were beautiful. She shouldn't have said that about his pictures.
Without Elvira and the kids, life at home had become uneventful. Peter found himself spending more and more time in the office, going out with reporters on late night assignments, anything to keep him from thinking about his ending marriage. Because even if she did insult his pictures, Elvira was the best thing that had ever happened to Peter.
On May 2nd 1998, Peter is working late at the Prophet again. News comes in, there's some sort of skirmish on the Hogwarts grounds. His editor turns to him "Just get a few pictures Peter, will you?" and he's off.
It turns out it's not just a skirmish, but a full blown war that has broken out at the ancient school. The reporter that was sent with him apperates away almost instantly. Peter doesn't. Instead he pulls out his wand and he drops his camera. Because right now, in that moment, he isn't there to take pictures.
Not anymore.
