PS: By the way, I don't even want more exposition (or a reason to fear them IC), if that's what you are thinking.

In fact, it's pretty likely that more information will only trigger more quips from Hifumi if it's something that feels wrong to her.

She has no reason to fear these Grey fellows IC (and she's not even the only one in the group who thinks so), Orson being forceful won't really change her mind.
