Here's a spoiler thread for anybody who wants to use it. These threads usually don't get a lot of use so we'll just have one combined thread for spoilers and historical spoilers.
Yes this series did air quite a while ago, but please do use this thread for any spoiler or historical spoiler you want to share or discuss because some of us will be watching the series for the first time. Really it's much better if you can wait until the relevant episode airs, but if you're just itching to post something spoiler-related then this is the place for it.
Background information that sets up the series or episodes in the series, that's not spoiler material and can be posted freely in episode threads or in dedicated threads.
