To comment on social spec mechanics:
1. Actual social combat should be rare. Most people will simply refuse to continue the conversation if they feel they are being pushed into such an emotionally high-stakes mentally stressful confrontation. It takes extreme outside (they feel they must stand there and take it) or internal (feeling desperate to defend themselves/argue the point) circumstances to allow for it.
2. At least in core Fate mechanics, it's sometimes possible to skip social stuff if you can compel someone on one of their Aspects.
If I were asked to represent mechanically what Keiko did in her interactions with Hana, it would not be an opposed roll-off. Instead what Keiko did was successfully guess that Hana had an aspect related to her son (Anything for my Son; or I Will Protect Hazou; or something along those lines), and then spent a Fate point to compel the Aspect and force Hana to reconsider her actions in that light. Note that this doesn't necessarily guarantee success or mean that Keiko will precisely control how Hana will react, but it does allow her to force Hana to alter her actions to better align with those of her Aspect as the player controlling Hana (the GMs) see it.
Aspects can be very important in the social Fate game. Hitting one of a character's core personality aspects is always a way to get them to reconsider their actions, though it doesn't work if they're already perfectly in line with that aspect.
