User blog comment:RWBY Adam Taurus/Penny and Qrow/@comment-6830001-20140508003158

We don't have enough informations about Penny and even less for Qrow. It hasn't even been said that Penny is a robot or something like that. We don't know if they personnally know each other. I don't think too that Qrow was the man in the car...

As for what he wrote to Ozpin, he may just have separately investigated about Cinder and shared what he found to him. We don't know much about their relation too...

We now just have to wait for volume 2 to maybe get answers to some of these questions...
