Stacey Newman was a temporary person at HQP. She was friends with Tanya and was left somewhat shaken after Ianto Jones arrived at HQP with a beeping device. She began to question what exactly it was that HQP did.
When Tanya pulled out a gun to kill Ianto and Yvonne Hartman, Stacey fled with them, but ran away to what she believed was her home after they told her that she was a temporary person. Ianto followed her and told her that her family and friends were not real, which she sadly accepted. (AUDIO: 9 to 5)
