Can anyone explain this to me?
I read this in wiki about Halloween 2:

Quote:
The plot twist of Laurie being Michael's sister required a retcon of the timeline between Judith's murder and the events depicted in the first Halloween; while Michael Myers is said to have committed the crime fifteen years ago and to be twenty-one. https://en.wikipedia.org/wiki/Hallow..._film)#Writing

"Retroactive continuity, or
retcon for short, is a literary device in which established facts in a fictional work are adjusted, ignored, or contradicted by a subsequently published work which breaks continuity with the former."
I don't get what they're talking about. So Michael was 6 when he kills his older sister (Judith) in the opening of Halloween, then he comes back 15 years later, he's 21, and Laurie is his younger sister. So what had to be changed?
