Growing up in a warzone, Seth never doubted that he would follow in his infamous father's footsteps, in fact, he thought it expected of him. He got his first criminal charge at age seven for burglary and had never stopped since then- deeming it "like a drug" when he knows he's disobeying the law. He's a very good manipulator and as a result, has many people wrapped around his finger just willing to do some of his dirty work for him. At age fifteen, he was already one of the most notorious drug lords in all of Buch del Santo.

Seth never wasted much of his own personal time with "materialistic things" such as drugs and money, instead he craved the power that came along with them, climbing the criminal ladder of the Buch del Santo streets. His favourite past time? Making people, friends and acquaintances for the most part, fear him for his own gain. The most famous and known victim of his tactic was his old "friend", Ainsley Castillo. The two had grown up together and bonded over the fact their parents faced the same demise- death by police. They grew on that shared hatred and Ainsley was rarely seen without Seth by his side. However, Ainsley's "devotion" to him was strictly fear-based and it only worsened as Seth would drag him into trouble. 

An incident occurred when Seth, Ainsley, and a select other skins (cousins of Ainsley) decided to heist one of the richest banks in El Calor, Buch del Santo. It was supposedly a "get in, get out" that turned into a hostage situation, in which Seth murdered three of them. This did not bode well with the rest of them, and the cousins plotted to turn themselves in, as Seth had gone too far. He took this as an insult and shot the cousins for their "disrespect and lack of dedication", leaving only Ainsley alive. The standoff lasted five hours and the two were eventually outnumbered by Buchan police and they were sentenced to prison. Ainsley managed to get out early on good behavior, whereas Seth was left to rot- at least, for the time being. Many years later, Seth managed to escape prison, reemerging with his infamous skeletal patterning, and to rejoin his loyal cult-of-drug-doers where he would then begin to seek Ainsley once more.
