Tintin and the Picaros: Part 2 - S2-E9
Plot hole: When the helicopter flies over the jungle, Haddock inadvertently walks in view of the helicopter and the pilot of the helicopter notices him, assuming it to be a Picaro. Haddock then trips into the river, but despite being watched by the pilot of the helicopter the entire time, the helicopter pilot doesn't notice him falling into the river and instead assumes he just disappeared.

Land of Black Gold: Part 1 - S2-E10
Plot hole: Thomson and Thompson fall asleep whilst driving their jeep and are arrested because whilst they were asleep, they drove into and damaged several people's markets and as well as driving into the wall of a building. Although the decision to arrest them would seem normal due to the vandalism, it does not make sense why both of the detectives would have gotten arrested. Even if they both fell asleep at the wheel, only one of the detectives was actually responsible for the vandalism caused by this. (00:19:00)
