It's dangerous to confuse vengeance with justice.
Aurora was so young.
It surprised her, that this would come to mind, but it was the truth. Aurora was many years younger than her in spirit, if not in body. She kept this thought in mind to keep herself from resenting Aurora - she remembered a time when she would have wanted exactly what Aurora did.
She remembered a time when she had wanted exactly what Aurora did.
It was a very long time ago.
She had put her need for vengeance on the men of the nation that had destroyed everything she'd ever loved aside, to help Philip find his princess. It had burned, but she had swallowed the fire and let it burn there. Maybe she'd been cool towards the men who'd guided them to where Aurora lay, but that coolness was only a symptom of the heat of anger in her heart.
Turning that anger in on herself had hurt, even more than losing her father, or losing Shang. It had been Philip who told her she couldn't blame herself for what happened. Though at first it only made her hate their guides more, she understood that justice was not always possible, and vengeance was a step in the opposite direction.
Those men had given them Aurora, and then she and Aurora had lost Philip. Hurting these women who'd come from nowhere wouldn't bring Philip back any more than killing the enemy nation to the last man would have brought back her own girlhood, or given her back the purpose she'd lost.
Who's going to lead us? You?
No, her.
Aurora's lack of respect still stung, but in some ways, the girl was right: she was no leader. If she could not command the respect of one princess, she certainly couldn't command an army.
Snow White could. Legend held that Snow had done it before, and with great success.
It was hard, to look at Snow White and Emma of the mystical "gun" and not be reminded of her own mother. Her mother had probably been taken by the curse, or been killed by the invaders of their country long beforehand. She was adrift, without ties to others, or the capability to form the relationship with subordinates that a commander needed.
Cora had torn her purpose away again when her ruse had been revealed, but Snow White could bring it back. She had to trust in a leader again, because, despite all Shang had taught her, she was still a soldier - not a warrior of legend, like the woman with the bow and strange clothes who stood before her.

A/N: So there wasn't enough Mulan in We Are Both for a chapter, making me skip ahead. There won't be a Mulan chapter for this week's eppie either, obviously. I wonder if/when we'll see her REAL backstory, instead of my invention...
