Damian opens the door to a safehouse the two of you as well as some of the other teammates had returned to after a failed mission, letting out an irritated sigh as he sees you with a cigarette between your fingers. You had this really bad habit of feeling extremely guilty when you weren't able to save someone. It kinda worried him.

"Those can give you lung cancer." He says for the thousandth time, sitting down on the end of the bed beside you and snatching the cigarette away.

You look like your about to protest but Damian doesn't give you the time. "You need to stop doing this, it's not healthy- and, no- I'm not just talking about the cigarettes. You did your best to save everyone you could. Sulking is not going to change anything." He flicks the cigarette into a nearby trashcan with precise aim.
