Noctura was still stuck on Alex's word when he said, 'Don't disappoint me.'
She wanted to show Alex that she was very strong, and she could take care of herself, she wanted to show Alex that all the time he used to train her had not gone to waste and that she was worth all the time he used.
Noctura was still a child, but unlike humans, her body and mentality were growing along with her powers.
Maybe it was because of the bloodline upgrade she had when Alex granted her the name, or maybe she was just a special case, but if she were to be able to turn into human form right now, then she would probably look like a 16-year-old girl.
With her high intelligence, she had higher EQ and IQ, but that was not always a good thing.
Noctura could see that she was not very useful to Alex, no, she was practically useless if not for her fur being so soft that Alex liked to ruffle them.
