This is a pretty good article for the anime alone I would say, but it fails to cover how much better of a job the light novels do on this front. Not only is sword oratoria so much longer (because obviously the adaptation was mid) and better written, but both also do a good job of showing Bells commitment to Ais. They also do a good job of giving us more of a view into how Ais feels about bell, but we probably won't get any confirmations on that until the final arc of the LNs.
