I thought she had been drugged up on some kind of heavy medication or something. My daughter was watching Lurches speech with me, and we notice her leaning slightly into people and bumping into them a little. She didn't walk alone either. Someone was always there holding on to her back, elbow, or hand.
We figured we were probably right, because the camera cut away from her pretty fast. Lurch left her behind and moved away from her. (Maybe she puked or passed out).
