I've said it once, I'll say it again, people who are extremely familiar with post-apocalyptic stuff scare me a little as they can judge how well I measure up against the genre. Which means it means even more to me when you say it's good!

Of course Sherlock is besotted with John, that's pretty much what happened in the show, wasn't it? Except then Sherlock had cases to distract him, this time he's got more attention to focus on John so John has good reason to be wary!
