Events of Criminal Case
Sebastian became a suspect after the player and Carmen found his revolution sign at the resistance's camp. At first, he drew a knife at them out of surprise, but they explained their situation. When informed of Adolfo's murder, he was happy saying SOMBRA would be brought down at last. Carmen asked how he knew of SOMBRA's ties to the government, so he explained that they were responsible for making the regime exist, though he ran away before hearing anything else. He went on to say the government is more of a dictatorship than a democracy, making them take Gabalium to keep everyone in line since the withdrawal is so bad the people would do anything to get it.
Later, the team got word that he was holding Pedro Torres hostage at the camp. Carmen managed to talk him out of hurting him, and decided to put him into custody for some time to cool off. He was spoken to again about a map where he placed several bombs around the city. He confirmed that he intended to bomb the City Hall, but when he heard of the President's murder he put the plan on hold and retrieved the bombs. But he made sure to tell them that he would be ready to fight if his power fell into the wrong hands.
In the end, Sebastian was found to be innocent after the team incarcerated Valentina Silva for Adolfo's murder.
- Sebastian seems to have been inspired by Argentine revolutionist Che Guevara.
