what happened to finn in peaky blinders

Finn Shelby ends Peaky Blinders as an outcast from the Shelby family and the gang, effectively banished after betraying their trust and swearing revenge.

Quick Scoop: What Happened to Finn?

  • Finn spends most of season 6 sidelined, appearing less and less involved in the core Peaky Blinders business.
  • This sidelining is deliberate: Tommy and the others have lost trust in him after earlier mistakes and see him as a liability rather than an asset.

His Big Mistake

  • In season 5, Finn carelessly reveals Tommy’s secret plan to assassinate Oswald Mosley to Billy Grade while drinking and taking drugs.
  • Billy, who is secretly informing for the IRA, passes this on; the IRA sabotage the assassination and kill Barney Thompson, Aberama Gold, and Polly Gray, a catastrophe laid partly at Finn’s door.

The Finale: Test and Betrayal

  • In the series finale, Isaiah and Tommy’s newly acknowledged son Duke force Finn to prove his loyalty by making him execute Billy for his betrayal.
  • The gun Finn is given has its first chambers emptied as a safety test; Finn turns it on Duke instead of Billy, exposing that he chooses his friend over family.

Excommunication and Exit

  • After this, Duke shoots Billy himself and announces that Finn is no longer part of the Shelby family or the Peaky Blinders, acting on Tommy’s orders.
  • Finn leaves in disgrace, shouting that he will “come for” Duke and effectively setting up a possible revenge arc in the planned Peaky Blinders movie rather than resolving his story in the series.

Fan and Forum Reactions

  • Many viewers felt Finn’s ending was rushed, saying his reduced screen time made the final confrontation feel abrupt and underdeveloped.
  • Others argue the arc fits his long-running portrayal as reckless, easily led, and not fully committed to the Shelby way, so his exile is the natural culmination of his failings.
