Annie, the Pizza Girl obviously knew Ianto on the front desk at Torchwood since she called him by name when delivering the two pizzas he ordered. (She seemed to have forgotten the coleslaw) She was surprised by the secret entrance to the Hub, and by the Hub itself as she wandered down into it.

Death: Lisa took her body and transplanted her own brain into it in Frankenstein fashion, complete with inept stitching. When Ianto found her she had some of Lisa’s memories of their relationship, but still wanted him to ‘upgrade’ with her. The other team members shot her.
