Episode Title:
In Plain Sight.
Episode Description:
In order to complete the Dragon Eye and discover the location of the King of Dragons, Johann needs more lenses while Hiccup still needs gemstones to complete his Dragon Eye 2. Continuing his ruse as their ally, Johann suggests taking a trip to the Northern Market with Hiccup alone and that he brings both his Dragon Eye 2 and all of his lenses. Despite Johann's attempts, Ruffnut and Tuffnut insist on accompanying them. During the trip, they are ambushed by hunters, but the twins rescue Hiccup and Johann and deduce that the only way the hunters knew they'd be there is if there was a mole within their group. Johann is able to distract the twins and lead Hiccup to the Sandbuster's lair, where he reveals his deception and demands that Hiccup hand over the lenses. However, Hiccup had already deduced Johann was the mole thanks to the twins, and is able to escape thanks to Toothless.
