Regina Mills, protective mother and wife.
Swan Queen: An essay in body language.
Note how one parent moves into reassurance mode (in this case Emma) by standing close to and using her body to herd the young. The other parent takes an aggressive stance against the interloper and possible threat while placing her body between her family and the intruder (in this case Regina). Both parents maintain awareness of the threat. The reassuring one may glance to the young but the aggressive one will not look away from the threat. Meanwhile neutral creatures (Neal), who have been deemed a non-threat, can maintain close proximity to the family so long as no threatening or sudden moves are made towards either the mated pair or their offspring.
