[Minako has her own worries on her mind. She's been researching the tea ceremony as best she can from a foreign world, interrogating anyone who looks like they might be from Japan, and---well, it's been a bit of a mess. The thought of Rei has been doing odd things lately, and that promise might not be the only reason...

That's why there's a distinct screeching sound on the other end of the door. Oh no, is it quiz time already? She'll just have to be brave and face the music. She takes a deep breath and swings the door open.]

What a surprise---ah, but not a bad one! Rei, please come in!

[Maybe she can charm her into not killing her. Maybe.]
