Answer: Split up
Step-by-step explanation:
In this episode, the Teen Detectives - Jake and Summer - are tasked with investigating the disappearance of art pieces all over the world. They go to a museum to investigate and notice a man take a picture of them but he then disappears.
Their investigations lead Summer to believe that the thieves are going to Greece and so she decides to go there as well while Jake investigates another lead. They therefore split up at the end of the episode.
