"So ... Naruto gets out of this because you're more scared of Kushina-san than our parents," Sasuke said flatly, tone deeply unimpressed despite Obito's explanation. "Yet this is supposed to be about controlling yourself when drunk?"

Naruto wasn't always able to control himself when stone cold sober, and he was the one who actually had Kushina for a mother. It was enough that Sasuke folded his arms even as he followed Obito -- because it wasn't like they were going to be getting a choice, here -- resisting the urge to roll his eyes only out of the vague thought that he was too old for something like that.
