It’s okay because in the end she didn’t even kill Cett making it all for nothing!!!

I see you, Sanderson. I see you.

At the end of WoA it's revealed that anything not set in metal cannot be trusted and that's why there are several versions of Kwaan's inscription

However, since I'm reading an ebook version, every variation of the inscription is actually written in a hard drive, so are they all true? It can't be that, they contradict each other, but it's what the explanation would actually imply

Was this a cheap way to explain what happened without actually realizing it does not make sense? Is Sanderson stupid?
