“True. But try to explain that to Captain Justice and Faith.” He takes a gulp of the scotch right out of the bottle and flops down on Tony’s lap, straddling his hips. “He cares too much. You and I? – We do what needs to be done.”
Tony circles his waist with both arms and pulls him closer, opening his mouth when Barnes offers him the bottle and swallowing the bitter liquid dry.
“Nobody ever believed I was able to care. So why should I?”
“Coming from somebody who is expected and probably should care more but doesn’t really give a fuck? – I’ll drink to that.”
