Just for reference, I don't think we should have to mark any spoilers regarding episodes which have been shown. People should have the knowledge not to look into the thread until they've seen the most recent episode. I know I wait the day or two between the US air date and the UK air date before reading!

Spoilers should only be for things that are going to happen in the future.

To be clear on things: If you haven't seen the most recent episode to be screened in the US, expect things to be spoiled for you in this thread!

Speculation about what's going to happen later on doesn't need to be marked as a spoiler, either - unless of course you happen to know something about future episodes.
