Connect is a verb meaning to bring together or into contact so that a real or notional link is established; to join together so as to provide access and communication.
In season 1 episode 5, eight different scenes use the word. In 105.1, young Olive on the flight home is sitting next to her dad. Steve tells her, “Being a twin is a heck of a special relationship. You always feel connected, no matter where you are.” Then shortly thereafter Ben receives a calling whereby he keeps hearing, “It’s all connected.” In 105.27, Ben uses yarn to connect photos of passengers to their seat. Earlier in the episode, Cal lead his dad through New York’s subway to find Thomas, where he too said, “It’s all connected.” When his dad asked him what he meant by that, he said he was just describing the tunnels of the subway. But the viewer knows that Cal was playing dumb. At the very end of the episode, Cal looks out the window from his seat and sees something, saying “It’s all connected.”
One reviewer writes, “the use of the phrase is vague, other than definitely relating to Flight 828 and its passengers. We seem to be building up to discovering that the passengers and the callings are all connected, but there’s no telling what else might be part of the larger picture, and what this connection means. Are the people who are close to the passengers connected? Did this connection direct their lives during the 5 1/2 years their loved ones were missing? There were, after all, two flights in the air that night. Just because one came home on time doesn’t mean it wasn’t affected by something. An episode title like “Connecting Flights” has to make you wonder. Did something more subtle happen to the passengers on the first flight, as well?” 1
