Could either have Renoa reported by Juno (after all, she did make Miyako cream her panties) or could have Miyako drop out of the program during the meeting and abandon poor Renoa there...though if you go with the second option the poor puppy is going to be all heartbroken and stuff (likely spiral into a self destructive depression)...it's one thing to be re assigned by a faceless organization, its another to be directly abandoned by the person who promised to take care of you and help you with this grand new adventure that is living in human society.
