Jurassic World: Fallen Kingdom - 23 Easter Eggs & References Explained
16. The Seatbelt Metaphor

Easily the most clever and mind-blowingly subtle piece of storytelling in the original movie is the visual metaphor of Dr. Alan Grant's (Sam Neill) seat-belt on the helicopter ride having only two identical "female" parts, with no way for them to plug into one another.
Grant instead ties a knot with the two belts, reflecting the movie's explanation that the park only bred female dinosaurs, but they were able to reproduce anyway, because "life finds a way."
This is scarcely nodded to in Fallen Kingdom when Claire, Owen and their team prepare to fly to Isla Nubla to rescue the dinosaurs. Owen meets scaredy-cat techie Franklin (Justice Smith), and after a brief introduction, the timid Franklin tells him, "We're not compatible."
The fact that this scene takes place inside an aircraft as the character introductions are taking place, and Franklin talks about compatibility out of turn ensures this is a direct, if clumsy, nod to that brilliant "compatibility issue" in the original movie.
