Love in Manhattan

where Martin Mystery and Diana Lombard are packing up for Manhattan, New York to spend their little vacation and heading to Queens, in America along with Martinʼs dad Gerard Mystery to do a university tour, yes they are planning to move there to live there. Martin promises himself that he's going be on his good best behavior, no mischief, and no pranks on his stepsister Diana, so Diana tells Martin that's very mature of Martin and he won't flirt with every girl he meets and Diana says that same thing she won't flirt with every boy she meets. So the two of them are "dating" while Martin puts his arm around Dianaʼs shoulder while the two of them are taking a college tour Diana wants to practice becoming a social worker, and while Martin wants to practice becoming an art historian, archaeologist, anthropologist, adventurer, writer, television producer collector of unusual objects but Diana tells Martin that is terrific, he's going to let her know when he wants to do any of these careers, so Diana and his dad Gerard is going to be proud of Martin for following his dreams.
