John was obviously incredibly jealous over Sherlock and Janine’s fake relationship; Acting disgusted and shocked at them kissing, not being able to comprehend the fact that Sherlock has a girlfriend (he never says ‘You’re dating someone?’, he just keeps saying “girlfriend??”), and when Sherlock proposes…looking like he’s just had his heart ripped out. This is not normal over ‘just a friend’.
Would you be willing to share some of your thoughts about Yuri's motivation over the rings, at least? I'd be curious to read your thoughts especially since that scene in particular has a lot of cultural terminology and background that doesn't translate perfectly for International audiences to begin with.
