Tear Jerker / Jumper

  • Griffin's Story has a subtle yet memorable one. Once Griffin starts hunting down Paladins, he keeps track of them by drawing photorealistic sketches - and eventually realizes that though he can easily recreate the faces of those who've been trying to kill him since he was a child, he can no longer do so for his parent's faces.
