Fanon
Cold steel is a rarepair in the rwby fandom. Mostly because these two never interacted until volume 7. Also ships like snowbird and nuts and dolts are more popular. With that being said most people really like the dynamic between the two. Penny despite being a robot understands her emotions well and can think for herself. Whereas Winter, despite being human, struggles with her emotions and almost allows follows orders without question.
