Chao-Ahn spoke only Cantonese, which made communication very difficult with the Scooby Gang. Rupert Giles tried to communicate with her using crudely drawn pictures. Chao-ahn accidentally mistook Giles' attempts at communication as threats, like how many people keep offering her milk despite the fact that she was lactose intolerant. She escaped the destruction of Sunnydale, having survived the battle against the First Evil.
