The first time Credence meets the real Percival Graves, he isn't struck too much by how much he looked like the man he knew, he'd had weeks to prepare for that.
He knew he was powerful and handsome, and that he had the respect and the responsibility of wizarding America (perhaps beyond that) so none of that took him by surprise.
He was shocked to see how painfully lonely the man seemed to be though, and how nobody else in the world seemed to notice. He knew how that felt and he couldn't bare to do nothing about it.
