It's unfortunate, but it can't be helped.
Piet is a non-player character in Final Fantasy VIII. He has blond hair and a white coat, and is the head researcher onboard Esthar's Lunar Base. He acts as Squall's tour guide on the base when Squall arrives there.
As Squall arrives on the Lunar Base, Piet greets him personally. Guiding them to the medical lab and assuring that Rinoa will be taken care of, he brings Squall to the base's control room where the beginnings of the Lunar Cry can be observed.
When Rinoa becomes possessed by Ultimecia, Piet is unable to deter her and is forced to watch her deactivate the seals holding Sorceress Adel at bay. As the Lunar Base is about to be engulfed by the Lunar Cry, Piet orders the facility's evacuation. Among the last to leave, he escapes with Squall and Ellone onboard an escape pod. Piet tries to no avail to stop Squall from leaving the pod to try and rescue Rinoa who is drifting in space.
Piet is later found in the escape pod's crash site on the Abadan Plains, having been unable help Ellone whom Galbadian forces have come to take away. To make matters less fortunate, with the space station gone, he's left unemployed.
Piet possesses the rare Alexander card, which can be obtained from him onboard the Lunar Base or in the Lunar Crash Site in the Abadan Plains.
