Ok, I feel there's a bit of a conflict at the moment.
The most obviously useful thing to do at the moment is try to meet with Hina, and find out if she's learned anything about Nitori's condition. Unfortunately, we were also supposed to keep the entire thing about Nitori secret from everyone, and I'm inclined to think Tenshi also falls into that category. Unfortunately, given our recent encounters with her, we're also in a bad position to tell Tenshi essentially 'sorry, but I can't trust you with this, and need to go on alone'. I shudder at the reaction we might get from her if we tried that.
Can anyone think of anything else worth doing, or some pretext that could separate us briefly, without engendering any bad feelings? In fact, I'm a little wary of the potential fallout of splitting up at all, so quickly after last time, although if we can find a good reason for it...
Alternately, we can simply let Tenshi know, but, all things being equal, she's one of the last people in Gensokyo I'd trust with sensitive information. And even if we DID trust her fully, it's still something of a betrayal of our promise to Utsuho and Parsee to tell her without a better reason than 'sorry, couldn't ditch her'.
Opinions?
