Arya couldn't get proper sleep throughout the night. She kept tossing and turning in bed, thinking about her suspicion. What if she is wrong? What if Michelle is not the mole, and she is thinking wrong? Rodriguez would never forgive her for this thing!
She had to think of a plan to bring her out into the open, in front of everyone, if she is, in fact, passing information to Alfa or Ronald. But first, she needs to make it a hundred percent certain who the actual betrayer is.
She planned to ask Michelle if she had told anyone about Rodriguez being her brother. If she has, that means that person could be the one Arya is searching for.
Rodriguez didn't want to acknowledge their relationship, and Arya understood that. It still hurt that he just told her that he was born as a rogue and, therefore, had no family. Technically, though, he is correct. Being born as a rogue means no adult is present in your life, and you're on your own.
