I have been reading "The 13 1/2 Lives of Captain Bluebear" (which I discovered thanks to a recommendation by an Australian YouTuber and his list of favorite novels). There's a part in the middle of the story where the Bluebear has an affect on something that happened in his past by what he does in his present (the future). Suddenly, the author is explaining to the reader (directly) about how this is possible and why it can happen and that it doesn't make sense "but there it is".
I realized that it bothered me not because it was confusion, but because i couldn't understand a need for the explanation. Clearly I've watched a ton of Doctor Who; this type of thing is a common occurrence in several story lines, and among many characters. Particularly, I recall a recent episode (vague spoiler alert, skip to the next paragraph if you don't want to be spoiled or let down from vagueness) when the Doctor does something simply because he knows he did it since he saw the results in the past even though he's using the past experience to tell him what to do in his present (the future from the past) so he can still succeed in the same way in the past and get to the future where he can do those things to help himself (and others) in the past (and in the future). It's a bit of a crazy circle, huh?
But, I'm long past the confusion, it makes perfect sense now (yeah right, but I've given in - it's too confusing otherwise (and anyway) so you have to or quit watching, which just isn't an option). I love that crazy show. So much.
