When Turtle and the guys drop off Vince for lunch, Ari meets them at the restaurant, but when Adam Davies calls Ari a minute later, Ari is back at his office.
When Ari, Eric and Drama are flying into the island, Turtle is buried in the sand, in the next shot, he is fully clothed yelling, "The Plane, The Plane " but between shots we see Turtle and Vince in the sea which means "time passes by" during shots.
