Please be respectful that some on here haven't read the novels. I tried to start a separate discussion thread for book readers, but it never took off. Best practice is to put book spoilers (anything that hasn't happened in the show up to the present episode) in white text. People can highlight the text if they want to read it.
FYI, it'd be helpful if you didn't go on to actually quote the spoilers after talking about how people shouldn't quote the spoilers. Now, if realisticidealist or a mod edits the original post, there's a copy of the spoilers in your post.
