Lights, camera, and... action! Wonder Man, the first Marvel TV show of 2026, is out now on Disney+. And, with all eight episodes of Wonder Man dropping on launch day, it's already time to dissect its finale, aka 'Yucca Valley'.
Below, I'll explain what happens to Simon Williams and Trevor Slattery in the latest Marvel Cinematic Universe (MCU) TV series. I'll also try and answer your biggest questions about the Disney+ show, too, including whether there'll be a season 2 and why Wonder Man leaves one major story thread unresolved. So, hop to it – but beware, full spoilers follow for the latest Marvel TV show!
What happens to Simon and Trevor in Wonder Man's final episode?
Surprising no-one, 'Yucca Valley' picks up immediately after its forebear 'Kathy Friedman'. The MCU TV show's seventh chapter ended with Simon learning that Trevor had been working with the DoDC – the US agency that monitors superhumans it perceives to be threats – to keep tabs on Simon. Remember, Trevor hasn't completed his prison sentence for his The Mandarin-based crimes from Iron Man 3. So, it was either help the DoDC or go back to jail.
Feeling betrayed by someone he considered to be his friend and mentor, Simon loses control, which results in him unleashing an ionic blast that causes damage to one of the in-universe 'Wonder Man' movie sets and temporarily knocks out the power within a certain radius.
After learning what happened and surveying the scene for themselves, the DoDC – led by the dogged Agent Cleary – now feel they have enough evidence to arrest Simon. What follows is a sequence of intersecting footage that appears to show the DoDC arriving at the apartment complex Simon lives in, and the latter slowly spiraling as he watches a news report covering last night's events before tearfully calling his mom before he's detained.
Just as Simon resigns himself to his fate, though, he receives a phone call from Trevor, who tells Simon that he knows how to make things right before ending said call. Confused, Simon turns up the volume on his TV – he'd muted it to call his mom and then take Trevor's call – and learns that the DoDC aren't coming for him. They're coming for Trevor.
As it turns out, Trevor has reprised his role as The Mandarin – well, the fake one he played in Iron Man 3. And, after recording a new video in which he takes full responsibility for the Hollywood-based blast, which Trevor/The Mandarin passes off as a terrorist incident, he posts said video online, which news agencies and the DoDC soon catch wind of.
