THEORY: This scene on the airplane is all in Jinyoung's dream. The flight attendant only gave her attention to him because in the real world, the flight attendant represents the EMT that's saving his life (Because they got into a car crash while on a trip - as follows in flight log: departure theories). Notice he wakes up surrounded by car crash rubble and not an air plane crash scene. Conclusion: Like in the orginal Fly theories... it's probable is the only one who survived. Sobs uncontrollably at the thought of my babies dying
