Well on the upside, 'being sick' is something Reira can just take and from there nod about. That sucks. But!

"Oh- that's good. Then you'll feel better later," she determines, in more ways than one. "...Being sick counts as hurting though. It's okay to say that." She is of course, assuming 'not hurt' was a matter of putting up a brave face rather than the simple matter of 'illness' not being equated to that in most situations- but she at least seems to mostly understand the concept.

And...hm. "Umn...I had...one day of classes? ...I met a lot of people, but I don't know what makes one a 'friend' yet."

Rex probably counts.

Also, that one black cat who showed her what cheesecake is.

(And probably Héctor himself by that logic)
