1x12 - Flint: The Time Detective

The Time Detectives had to go back to 15th century in Transylvania to retrieve another Time Shifter named "Bindi" which she is in the possession of Count Vlad Dracula or just simply Count Dracula which his fellow people in his villagers believed that he is actually a vampire. Upon meeting with Vlad Dracula, the mysterious guy who helped Sara in some episodes, revealed his identity as Merlock Holmes of the Time Bureau and assigned as undercover detective to observe Flint Hammerhead in his missions. In the end of this episode, Bindi choose to side with Merlock because of her faith to him and also because Flint already sees that she wants to go with Merlock rather than their team.
