Plus my personal experience with heated stuff isn't that time causes one to cool off, it's that the resultant feelings fester until properly addressed.
I've experienced mostly the opposite, but that's also between people who already
want to believe the best of eachother. Also, that leads to not discussing things for years at a time. And, given, between people who
don't feel particularly inclined to believe the best of eachother, I've seen a lot of... either festering, or willfully trying to drop the entire topic forever and then picking up right back where they dropped off if they need to ever interact again.
How long has it been for Hijiri since we've talked to her? I feel like a
little cooldown time, maybe enough time to take a breather and get some sleep and food if possible, would be good, but I agree that leaving it too much longer would be prolly unwise. Has it been a full sleep cycle yet?
I
would drop the science in favor of Hijiri if it was fully an either/or choice, although I do feel like at least one "let me poke one more thing for a last idea I just had for like five minutes" would be something there's time for afterwards. Then again. I tend to procrastinate going to sleep until 4pm on accident sometimes. So. Maybe not what we want, unless we
do want to ask Firn to write up "test multitasking with chibi!Brina while we try and get real-body sleep".
