As a demon Maid in a contract you had to save Ciel whenever he found himself in peril. Of course you would even without the contract. You've grown quite attached to your master. And for goodness sake you could never figure out why. But when he was kidnapped by a cult you didn't need to wait for his order to save him. You were there in a flash. A beat up and tied up Ciel at your feet.

You always were good at finding me...
