No, it makes perfect sense! I get it now! Everything that has 
happened in the books has *happened already*, and a time-turner can't 
change that; otherwise, it would create a paradox. For example, if 
Harry decided to use a time-turner to go back and save Lily and 
James, he would fail *because in Harry's future Lily and James are 
dead.* Whatever he did or didn't do in the past would not change the 
outcome that necessarily must occur.
