She went in to suggest he get those injuries looked at and he suddenly walked off jerking away. He then goes and apologies to her in his thoughts and a image of a young girl and gladiator is shown. He didn't want to act that way but protecting his identity seems to be important enough to be rude to someone he seems to cares for
That doesn't prove anything. His action could very well be born out of shame leaving him unable to face her regardless of her condition. I simply don't buy that his Daughter wouldn't recognize him if she had memories of her father.
This is either a product of the DF responsible for the memory loss or he left when she was very young.
