You have no where else to go. Stay with the grandfather

Though the thought of being eaten frightens you to no end, you say, "I'll stay with you."

The grandfather's jaw hangs open in shock. "Do you have any idea what you're saying? I'm going to change tonight, aren't you the least bit scared?"

You nervously chuckle. "I'm terrified. But, you saved me, you saved my children, and... I have no where else to go. If there is any way I can repay you, I will. Even if that means giving my body to you, one way or another."

The grandfather grows quiet, and you wonder if you made the right decision in staying. But seeing the pain in his eyes, you feel like you have to do something to help him.
