I really enjoyed the build up to the porn, Sherlock being so gentle and intimate with simple actions. Sherlock just appearing at an unreasonable hour and straddling him is always a hilarious bonus. Despite actually finally getting somewhere with his feelings, I see Sherlock is still pretty much failing at human interaction. Oh well, if he didn't he wouldn't be the Sherlock we all know and love.
Also still hate Seb even if he is still perfectly innocent (maybe because I'm expecting him to turn out to be a right bastard).
