Never knowing Ryou, all Hawke sees is same person from the night he killed that spellcasting creature. The only difference is that now Hawke can clearly the see his face. As Bakura moves by the alley Hawke darts towards him. There's no witty remark, or a battle cry of any kind. He just jabs a fist at Bakura's chin to throw him off balance so he can hopefully haul him into the alley by his long silver locks.
