Just think of it as a hazing ritual/rite of passage for the newbies.

But it is Isokaze that made good cookies that locked herself in.

Poor Isokaze... I'd eat her food. If she goes through the trouble of making food for me I'd eat it.

Aww! That makes me want to hug Isokaze, pet her head and tell her everything is okay and that I'll eat her cookies anytime.

Wow...that sounded way more suggestive than it should've...o.o
