Spiff Shepard (anyone who gets the reference gets a high five and a cookiee) is, on the surface, a tough-as-nails, no nonsense, jerkass soldier. On the underneath, however, he secretly fears becoming close to anyone, after his entire family and all his friends were butchered by batarian slavers, which also gave him a deep-abiding loathing for batarians, although by the time ME2 rolls around, he's sorta got over that, after the Asteroid X57 incident. After his squadmates died on Akuze, his stoic persona set in, and he began to actively push people away from him. During the hunt for Saren, however, he seemed to recover alongside friends, even having a relationship with an Asari Scientist. However, after the death of Ashley Williams on Virmire, he went off the deep end, but in a different way from before. He started to become suicidal, taking daring risks if it mean he could save anyone. He became the ultimate paragon, but not because he is a saint, but because he has serious psycological problems. After being ressurected by cerberus, the people responsible for the Akuze incident, he began to turn vengeful, and angry towards the organisation. While utilising their assets, he took every oppurtunnity possible to sabotage them, a goal that seemed to take precedence over finding the collectors. He preserved the lives of everyone he could, though the death of Ashley Williams haunts him to this very day.
