Well, Colt was a Squadron Leader attacking human villages, he never displayed any human feelings. In the manga, his mother may not even have ever seen him (him possibly sparing her is anime-only). I think she recognized Shidore because of her attitude, which clearly implied she wanted to meet her but was too shy to do so.
