As Severance heads into its season finale, its devoted fansincluding us obsessives here at io9have come up with a million theories about the shows many mysteries. But amid all the Cold Harbor speculation, the Mark/Mark S./Helly/Gemma drama, and the mystifying true purpose of those damn goats, a few things seem already settled thanks to The After Hours, the shows penultimate season two episode. However, in the world of Severance nothing is every really settled, is it? In case youre not caught up with The After Hours, beware One of the episodes most heartbreaking moments came when Irving (John Turturro) hopped a train out of Kier with his dog Radar, leaving Lumon and his entire life behind. His escape came with the help of Burt (Christopher Walken). The two sparked a workplace romance as their innie personas, and later, when they met as their outies, felt a similar attraction. That situation, explored in the latter half of season two, was exceedingly complicated by the fact that Burt has been with his husband for decades, and is also still in cahoots with Lumon in a more malevolent capability than his innies role as the folksy head of Optics and Design. However, just when you thought Burt was driving Irving (and Radar) to some kind of Sopranos-style doom, he instead bought Irving a train ticket and gently warned him never to return. The two men shared a poignant farewell, acknowledging their mutual feelings before dutifully setting them aside.With Irv effectively in exile now, fans have wondered if itll be the last we see of the character. Its a big loss for Severance, since Irv often served as the emotional heart of the showas well as being someone unafraid to call bullshit, especially valuable in a place like Lumon thats full of it. Speaking to the Hollywood Reporter, Turturro said he wouldnt feel satisfied if the train scene was really the end of Irvings story. If someone wanted the story to be complete? It could be! But I think theres so much more here, he explained, noting that theres a lot more of the characters backstory hed like to dig into.Irving knows a lot that you dont know. Theres a big reason why hes making all those paintings, you know? All that hes searching for. Everyone gets severed on this show for different reasons. Grief, maybe theyre lost, maybe theyre the daughter of the owner. Maybe its also searching for someone, too, Turturro said. Theres just one more episode of Severance season two to goand though Apple TV+ has yet to confirm a third season, it feels like an inevitability at this point. Irvings return is less of a certainty, but wed sure love to learn more about him, and Turturros just given us fresh hope that might happen. Want more io9 news?
