Alrighty, I'll try. I think they're both pretty self conscious about themselves and they could get along quite well because of that. Floyd usually sticks to doing voice communications on the network, as does Ruka, and he operates in a featureless mask (essentially erasing his identity in any interaction that he has). When they had interacted, Floyd was supping on some humble pie. He is considered one of the foremost assassins in his universe and being brought here (where very few people recognize him or know what he is capable of) kind of forced him to accept the reality that he has to work harder to build up a rep over here. Which was why Ruka was quite lucky and Floyd asked her what she wanted to be called. She sounds like a kid to him (BECAUSE HE'S FUCKING OLD) but, because he wants to see herself as a young Miss, he'll respect that.

And he still totes thinks that she should sell information for money next time.
