What's going on!? (We Happy Few)

All kind time of day.
Now pass for Sally 2nd Chapter, near the end apparently.The plot of the game is cool, adult.
So, the question for those who have passed, what happens to peresekaemost events of heroes? Why they're so different...
Spoilerfree the game for Arthur fish oil asks Sally when HE comes to her and meet at HER HOUSE!
While playing for Sally, SHE finds it and asks for help in the GARDEN!
And when you play for Arthur during their last meeting, she never says a word about the child when he leaves and when playing as HER, cries out in his trail my baby
It's like something razyasnyat at the end? They say each one to see what he wants? Glitches can what from Radostina?
Or is it a brilliant the progress of developers that would be the same boring did not seem?
PS.
Please do not spoiler, just answer Explain/Not explain. If not , it is of course a complete failure, I understand that this raznoobrazhivaet passage, but this robs the narrative logic...:(
