I can buy that acquiring a stealth enchantment for travel use will be to our benefit. Obviously, QB would appreciate less wasted energy on his part as well. However, the bunnycat
always has an ulterior motive.
The biggest issue here is the meeting with Kyouko, and then later Asunaro. I'm absolutely loathe to miss either of those, and an hour is very unlikely to be enough time to squeeze in yet another meeting, much less actually get the enchantment.
My current inclination is to get the name from QB, but not commit to meeting that particular girl until Mami and/or Homura potentially vet her. However, we should also not dismiss the stealth enchantment idea entirely - make it clear that we're not entirely impossible to cooperate with.
As an outline, something like:
[ ] You'd be willing to acquire a means of masking your travel from mundane observation, but have prior commitments for this morning in particular. You could try to schedule a meeting for later on this week, but you'd like more information first.
-[] What is QB willing to tell you about her?
[ ] Be noncommittal. You'll think about it and get back to him later.
-[ ] (Assuming she wasn't the girl in question
Speaking of girls with concealment powers, will you tell me anything about the whereabouts of Kuroki Matsuko?
[ ] You were planning to attempt to find a way to make your grief invisible using "normal physics" principles. Doing so for your grief cloud would reduce the amount of memories that need to be altered when you travel, correct? Any suggestions?
-[ ] Shoo QB away after the conversation, proceed to science.
