Also I guess that explicitly clears up the confusion I had about The Scratch. I was always under the impression that it erased that timeline completely.
Well, you could have just... listened to what people have been saying in these topics.
And yet it seems it still isn't clear to you. So I'll repeat myself. It DOES erase that timeline completely. Starting from the point of the scratch, the timeline no longer exists. But that doesn't mean you can't reach it before it got scratched! If the timeline suddenly never existed, the scratch wouldn't have been made in the first place. Have you forgotten that Jake has been communicating with young Jade for years?
