Oxygen, the latest Doctor Who episode just premiered on Saturday, and we need to talk about it. Normally, I try to make these kinds of posts spoiler free, but not this time. Please consider this a friendly and courteous spoiler warning. There is an image right after this paragraph, and then there will be spoilers, so if you have not seen the episode, please stop reading after this paragraph, go and watch the episode, then come back and we can discuss.
