[X] Only thing -- anything involving you knowing things that you didn't have a way of knowing doesn't leave the creepy sphere.
-[X] If questioned: you really aren't prepared to get into why right now. Suffice to say that roughly nobody else is in on it either. [X] Listen to Kyouko while hunting
-[X] Let her do the talking, mostly. Disagree with things you disagree with, agree with things you agree with, but let her do the talking.
[X] Let Kyouko take her frustrations out on the witch. Help some. Be ready to just kill it if anything bad happens.
[X] Let Kyouko know you might be dropping something heavy on Sayaka today, so she might have a lot on her mind on their next session.
-[X] No more bombs you want to drop right now. Another time.
[X] On the way, ask Kyouko about the possibility of summoning your magical weapon with speed, such that it would already be shooting towards an enemy as you summon it.
-[X] Tangent: After all, they're not immobile when you summon them, but already moving at incredible speds, what with Earth's rotations... and those of the Milky Way...
-[X] Maybe it's a matter of visualization. Theorically, you could just (snap fingers) will a small version of your hammer's handle to materialize shooting at something.
[X] Hit the Witch hard, but let Kyouko hit her harder. Make sure nobody gets hurt.
[X] Whenever appropriate, compliment Yuma about her new dress.
