Aww! I love how this fic is fluffy and yet still in character for everyone. As much as I loved Q looking to John for how to deal with those things called feelings in the wake of a sort-of-friend's demise and Sherlock not being a rubbish brother in the least, my favorite moment had to be Q getting annoyed at John's two finger typing. It makes so much sense and I had this immediate image of Q practically gritting his teeth at the sound of John's hunting and pecking.
