I apologize deeply for the lack of updates on The Elements of Discord, but the truth of the matter is simply that I'm stuck. (Well, and paid work is taking up quite a lot of my time too) One day I'll return to it.
In the meantime have a little Sour and Gloomy. I don't know if they actually knew each other as children (probably not), but the picture simply happened and who knows...if Rainbow Dash and Fluttershy can have known each other as kids and ended up being element bearers, why not these two? Oh well, we'll see.
