It is well written and cute, but I don't see John as one to get PTSD. Remember how Mycroft said John craves and misses the war? I do see him getting alarmed at a threat to Sherlock but not going full PTSD mode. But it is well written :)

Amazing! Love it!

Loved it! :D I don't think the fact that John has PTSD is covered enough, and this really did it. Really really great, especially the way Sherlock reacted! Can't wait to read the rest of your stuff!

I really enjoyed your story, particularly Sherlock's comforting of John at the end. However, I might suggest changing the rating to T for language and perhaps some of the themes (although I am certainly no expert on the ratings system). Thank you for sharing!
