"Um.. sure."

Seems like a reasonable enough request. He's seen little sisters riding the backs of big daddies around Rapture, and the thought of carrying this small girl around actually warms his heart. He gladly picks her up, and holds her as easily as if she had no weight. A few minutes of walking and they're inside, and he hesitates before helping her back down onto the ground. At least, most people he knows wouldn't want to be carried longer than that.
