After all what's left to her was just one fourth of her original power and she even travelled from half across the globe to get here in just a short period of time.
She was in Mongolia earlier because she was following 'their' tracks. Though she knew that she almost annihilated them all, she wouldn't take any chances. Luckily she sensed his presence when he made the car explode. She instantly went her way to get here though it expended a lot of her strength.
