Well considering the text, "and this time, you lose" made me believe that Hush was Tommy (because of the games they would play when they were kids), but then I read the caption text, and now I think that Hush is Jason Todd. So I decided to compare that gravestone to the one in Batman #615, and its different. Thomas Elliots gravestone has an angel kneeling with its arms out. The one in the pictures has its head straight and its hands together in a prayer position. So that must mean...
