Scans on what? I think we are all on the same page when it comes to Lucifer. So there really is no point. No point of showing scans on how John can come back from being erased.. Now if you really need scans on John's ability to manipulate luck well...
Also there is something called wikipedia and dc wikia
ask anyone.. really
If you have no idea what synchronicity is.. wikipedia is there for a reason. Read it it's all wrapped up with timespace continueum.
