Someone like Zemo doing the courtesy of calling Bucky 'James' compared to someone who was also in the military and knows the levels of respect like John Walker calling him 'Bucky'. Zemo knows they aren't friends or even associates. So he uses 'James', as he should. While Walker uses the nickname like him and Bucky are friends, associates or even 'co-workers'. Instead of using Sergeant, Barnes or even James, like he should be doing. Who knew I'd end up having more respect for Zemo in that aspect?
