And this has nothing to do with gender, it's based on the characters actions.
But they're not real people. The writers wrote some of the adult women in this show as fairly incompetent, especially in comparison to almost all the men and child -- which I find somewhat irritating. That said, I think in this situation it's just a thing someone might say to his or her son when he's reeling from a horrible situation and about to be left. Give him a sense of purpose.
