Seeing you breaking down is painful for Bruce. Seeing you fall, is like watching a mountain getting destroyed; because you are his older sibling, no, even more than that, he's hero, mother he lost and the father he watched getting shot."Come on." Bruce takes away the bottle of alcohol from your hand, "You're destroying your poor body." And it's also killing Bruce seeing you destroying yourself. You being like this? It's much more painful than the night he lost his parents to a random robbery, because this is about the person Bruce watched raising him. "Can you at least eat something, for me?" Oh poor Bruce, he never knew how to comfort another person, but give him credit for trying.
