Everyone is angry at me because I made a choice. A lot of you think it was the wrong one. Well, wouldn't be the first time, and it won't be the... well... maybe it'll be my last. The truth is, I'm still figuring out how to do the right thing. I'm not using that as an excuse; I accept full responsibility. But before you condemn me, lemme ask: who here hasn't made a mistake? Yes, I went into the bridge to save Claire's brother, and if I'm being completely honest, I would do it again!
―Jim's speech during his trial against the Troll Tribunal

Mistrial and Error is the thirty-eighth episode of Trollhunters and the twelfth episode of Part Two.

Official Synopsis

Jim stands trial for unleashing Gunmar while his friends race to clear his name. If convicted, he'll be sent to "The Deep", a dark realm of no return.


While Jim stands on trial for his life, Blinky and Claire try to investigate a way to get Jim pardoned. When they find out that there is a spy, they realize that this trial is a sham and all a plot to get Jim out of the way. Can they find out who the culprit is, or will Jim be executed?




  • It is revealed that Usurna is actually working for Gunmar and she has been planning to get rid of the Trollhunters all along.
  • When Jim was exiled to The Deep, he confronts a monstrous troll version of himself with the Eclipse Blade, which most likely foreshadows Jim's ultimate fate in Part Three. This most likely shows that Jim's worst fear is losing his humanity.
  • This marks the final (physical) appearance of Vendel, due to being killed by Usurna.
  • In a "blink-and-you'll-miss-it" moment, when the tribunal does their first round of rock-throwing at Toby and AAARRRGGHH!!!, a gnome can be seen flying by Toby as one of the objects tossed.
  • Error: When Usurna smashes Vendel's body, the head piece rolls face down on the floor but as Blinky later found him dead, it was atop the pile of rubble.
  • Running Gag: Blinky threatening to blow trolls up using dwärkstones.
