Night Patroll is the fortieth episode of Trollhunters and the first episode of Part Three.

Official Synopsis

With the trolls hiding out in Arcadia, AAARRRGGHH!!! goes undercover to see what Gunmar is up to. A potential rival brings out Jim's jealous side.


With the trolls hiding out in Arcadia, AAARRRGGHH!!! goes undercover to see what Gunmar is up to. While that occurs, Claire catches a huge cold from her experience with the staff and signs up with her friends for a music contest occurring. 




  • The events of this episode take place two weeks after the Part Two finale "In the Hall of the Gumm-Gumm King". 
  • Barbara starts to paint pictures trolls (her first painting being Blinky), hinting that her memory is returning. 
  • In the opening scene, we see a flash of light land in Arcadia. This is presumably the aliens Prince Krel and Princess Aja from 3Below landing in Arcadia for the first time.
    • Goof: The first episode of 3Below shows the ship crash-land in Arcadia at dawn, whereas in this episode, the ship is seen landing at night.
  • Goof: The Heartstone appears to be alive when Dictatious is with Usurna within it.
  • The character of Mr. Hammes, who is running against Ophelia Nuñez for city council is most likely named after his voice actor, Chad Hammes.
