This week on Source Material Comics, Mark and Jesse dive headfirst into the psychological depths of Joker: Killer Smile, a chilling DC Black Label miniseries from Jeff Lemire and Andrea Sorrentino. With a focus not just on Gotham’s most chaotic villain, but on the psyche of the man who dares to try and cure him, this episode explores what happens when good intentions and hubris collide with pure, unfiltered evil.

Dr. Ben Arnell is a man of science, order, and reason. But when he takes on the seemingly impossible task of rehabilitating the Joker, he finds himself spiraling into a personal nightmare where reality and delusion bleed together. As Mark and Jesse dissect this psychological thriller, they discuss how Joker’s manipulation isn't just about carnage—it's about control, gaslighting, and breaking a man piece by piece. The hosts reflect on themes of mental health, the illusion of control, and that haunting idea that maybe all it takes is one bad day to fall apart.

Mark brings rich context from past Joker tales while Jesse shares his appreciation for Lemire's storytelling and Sorrentino’s haunting artwork. Together, they ponder deep questions—was Ben ever truly sane? Or did the Joker merely expose what was already lurking beneath? Tune in as they break down a story that might be short in length but is terrifyingly deep in impact. This isn’t just another Batman story—this is a chilling descent into madness, and the Joker has the last laugh.
