Telling her? If she was telling her what to do, she'd know it. If the Leader was giving out direction, she'd make it well known. Minako was simply stating the obvious, something people did quite often. "If I was telling you what to do Rei, I would not have been so nice about it." she was, or she had been relaxed, and now she was just annoyed. Minako had not stressed her position as Lead of the Senshi since their first enemy, but now Rei was just being ridiculous. Her expression and tone clearly left a 'I'm not putting up with your temper' message. Not the place, or the time.
This was very clearly not her Rei. She got along with her realities Rei. While they often clashed, they had an understanding, they were close. This Rei, she didn't know what to think. Clearly, whatever team she came from lacked any kind of order.
She turned her head slightly to the side as the male approached, raising her chin just a little. Biting back the urge to say anything rude, she studied him for a moment, before answering. "I understand that feeling." she said politely, crossing her arms over her chest. "We're both fairly knew here," she said, casting a glance at Rei. "Not a whole lot about this place makes sense."
