Who is Doug Trumbull?

Elsewhere, Paul Billings heads to Judicial. He finds Doug Trumbull, a member of Judicial security, sitting with Sims. Doug is auditioning to be Sims’ new shadow. He looks suspiciously similar to the man who attacked Marnes the night before. Have we found our killer?

After an eventful lunch break, Juliette and Paul reconnect. Paul explains that the Judicial is doing its own investigation and they have its own suspect. Juliette isn’t interested. She knows they are setting Patrick up. They have their patsy.

Juliette finds Doug outside Patrick’s home, waiting to arrest him. She points out that Patrick has moved houses. Juliette knows that they planted evidence in the wrong apartment. Doug realizes he’s been caught and runs.

Juliette chases after Doug through the Silo’s very own foot race. The contestants head up the stairwell while Doug and Juliette descend it. Doug collides with the racers but manages to trick Juliette. Coming out of nowhere, he pushes her over the edge.

Juliette dangles from the railings of the stairwell from a dizzying height. Thankfully, the crowd spots Juliette hanging over the edge and comes to the rescue before she falls to her death. Juliette wastes no time in gaining an arrest warrant for Doug.

The killer happens to be with Sims, though. He’s aware that Doug has failed to frame Patrick or kill the only person who knew the truth, Juliette. Sims talks about his own past. His father was a janitor, yet he may have had a secret calling, which Sims calls the most important job in the Silo.

Sims mentions Doug’s other failings, implying that Doug messed up with George’s murder as well. Sims and Judicial seem to be the ones calling the shots, instigating both of these murders and maybe more.

Who is the killer in the Silo?

After accepting Doug as his new shadow, Sims pushes Doug over the edge to his death. The killer could not be trusted, he was a liability, and Sims needed to cover his and Judicial’s tracks too. Juliette takes her theory to Judge Meadows. They all agree that Doug was the killer. He killed Marnes and George. It’s a strong possibility that he killed Jahns as well.
