Character Connections Across the Stories? (Spoiler)

so the father of the champion of justice was the boy eating the omelette in the bar who missed most of the go-rangers tv show.
that would make him maybe 40 in 2010, and his highly trained son, 20ish. He married the girl who was being attacked near the tunnel, is he supposed to then be the record store owner? the customer is clearly just a young guy although it puzzles me why he apparently wasn't aware of the comet.
the science student was saved by the champion, from execution by a doomsday cult guy.
The leading doomsday cult member was the guy in the mobility scooter, a hedonist who knew all along 2012 would be the end of the world. His two assistants split off and formed the ferry hijack cult thinking they needed an Ark (they got the date wrong but the tsunami right).
I don't know who the guy walking off in disgust from the first doomsday cult failure was (he had a friend who stayed behind).
also I don't know who the girl with the 60s hair who looked sadly at the crowd listening to fish story fitted in, or what if anything became of the band or the singer, or the manager. Oh wait I guess the band manager was the grand father of the champion of justice?

The other posts are all various degrees of wrong. More correct (perhaps missing a couple):

The girl who sleeps and forgets to get off the boat is the astronaut who calculates the missles at the end and saves the world
She is saved by the champion of justice, who is the son of the driver of the car in the 80s
The car driver hears the girl being assaulted by the side of the road, saves her, and they give birth to the champion of justice from above
The car driver divorces his wife before 1999 and goes to the beach where he meets his old friend, the abusive guy from the back seat of the car who the girl from the restaurant tells him to stand up to
While at the beach they witness 3 doomsday cult members, 1 of whom hijacks the ferry in the 2000s
The "leader" of the cult is the one in the scooter at the end of the movie
The band manager's son is the record store clerk

The overall flow is that a Japanese man lies, gets a job as a translator, fake translates Fish Story, the accountant at the publishing company takes a copy of the recalled book, her nephew "steals" the book from her house while she is on her deathband, the guitarist of a band he manages sees the book and writes the song and his son (eating omelette rice) hears the song will save the world one day (while the band and manager plot out the entire movie), the song is heard by the car driver who hears a scream during the silent part while driving in the dark, the driver stops and saves a girl and they have a son, the son saves a girl on a ferry from terrorists his father had met on a beach during a fake doomsday yeas prior, the girl saves the world from a meteorite while the band manager's son, the record store clerk, watches and is bothered by the former boss of the ferry hijackers.
