This video addresses why Jin did not leave Sun behind for their daughter's sake.
Guys I have not seen this mentioned anywhere before so I am willing to talk about this.
In the first Episode- Pilot Part 1
11:58 minutes into the show, Sawyer (James Ford) walks smoking on the beach. If you see there is the wreckage part of the plane with '8 windows' and SAWYER was standing next to it.
In the series 4 8 15 16 23 42, Hugo is 8 & Sawyer (Ford) is 15.
15 is next to 8. And Sawyer was standing next to 8 windows.
I guess it was a kind of foreshadowing and the shot remains the same for nearly 10 seconds, I felt like why such a long shot of Sawyer smoking standing in the middle of the wreckage, but it was Foreshadowing. Please let me know if I guessed wrong.
This is something that took some time and effort so please dont judge me too hard, it might be too easy for diehard fans, but I just did it for fun and entertainment. I hope you enjoy it.
