Ashes and Dust
Evan Abby was, at first, the primary suspect in the case. His group was under scrutiny from the local authorities and the FBI and was deemed an eco-terrorist group. After questioning by the BAU, Evan attempted to disband the group in order to help flush out the real Unsub. He then began performing a series of suspiscious activities which caught Hotch's attention. It was only after Garcia's investigation into his that the team realized he was not planning to flee, but to set his affairs in order. Hotch found Evan at a local park, watching his son play baseball. Evan explains to Hotch that he only has six months to live. Hotch asks about the EPG's disbanding and if anyone there had become angry when Abby made the announcement. Evan explains that Vincent Stiles was enraged and stormed out of the meeting. At this point, Hotch contacts the rest of the team, but Evan has other plans.

He meets with Stiles at a local dock and tells him that he needs Vincent's "skills" to perform one final act of revenge. He arranges for Stiles to meet him at an old warehouse that had recently been rezoned into an Elementary School lot. Stiles and Abby meet, with Stiles being dressed in his fireproof suit. Abby had doused the floor and walls with gasoline and asks Stiles if he's ready to perform one last time. Stiles points out that he has enough oxygen to last until the benzene burns out, but Abby tells him that the chemical burns mush hotter than his suit is rated for. He then begins playing with his lighter, taunting Stiles. Stiles asks, "How do you plan on getting out?" Evan simply replies, "I don't." He then flicks the lighter's wheel and the warehouse goes up in flames, killing them both.
