What happened/will happen to the different versions of Lee Gon:
LG1 - the savior in episode 1
LG2 - the 8-year-old LG in episode 1 and the savior in Episode 14
LG3 - the 8-year-old LG in episode 14
What happened to LG1? Did he have an associated TE in his alternate world? Also, it seems it was LG3 who was with TE in the hospital in episode 15 since he can remember how nicer TE was to him during their first meeting. But wasn't the LG in the hospital LG2 who had been trying to go back to TE?
Theory:
These are all the same LG. The savior and the 8-year-old are just at different points in time. So, the LG and TE who met in episode 14 are the same LG and TE who met in episode 1 since both scenes happened in Gwanghwamun Plaza in 2019. They were not alternate versions. History just got re-written - Tae-eul of episode 14 believes in fate and parallel worlds and hugged LG first.
How was this conclusion reached? The LG who was with TE in episode 15 had memories of both LG2 and LG3, i.e. he was both LG2 and LG3.
When LG3 reaches exactly the same age as LG2, they would become one and the same, as long as nothing changes in between that would stop LG3 from reaching that time and space. This is why LG2 is careful not to create a butterfly effect that would occur if he makes a change in the alternate time. As he told Jo Yeong, "If I miss each moment by even a second, I can't meet her".
Questions:
Why didn't the savior return to the point in time before the Manpasikjeok broke into two? Was it because it would mean he and TE would not meet since the scene where young LG grabs the ID from the savior would not happen? Why doesn't he just plant TE's ID in, say, young LG's favorite book? But then perhaps the young LG would not form as deep an attachment with TE if she is not associated with a savior figure and would not try to find her. But if they are fated to be together, wouldn't he?
Can't wait for June 12 :)
