In my opinion it makes sense. Knowing Joo has such intense anger issues, he’d probably be pissed off at the timing—like, 'Of all the days to get stabbed, you chose today?' or like ' didn't we teach you how to fight? why didn't you defend yourself?' You get me? Plus, we can see Dan is still terrified of him, which is likely why he chose those words.

Dan just got stabbed and the first thing he says is sorry we can’t crack tonight
