I see hearthstones story leading up to Kaladin's arrival as thus: Lirin is tending the wounded in the town when Roshones guards drag him up to the mansion because Roshone is injured, he is unable to save Roshone, Laral is the only lighteyes left behind and is a less than ideal leader. Most people in the town move up to/into the manor as Lirin has been unable to leave yet and are being treated there, Laral has secluded herself in her rooms. I'm also curious as I can't remember how the light in the manor was described if at all, if they have stormlight still or are stuck with oil/candles.
The parshmen - we have seen no signs of bodies or corpses (Alethi normally have a pyre right?) yet - so I would assume that the transformation from slaveform to stormform has shocked them quite a bit and they've well Stormed off - I mean if they had much sense they probably wouldnt of just crashed through a wall would they? They may have returned since but been fought off, or they may be running off and being drawn into an Alethkar wide voidbringer army.
From imprecise leadership and noone knowing what to do they won't be/aren't ready for another storm. I picture 2 options on Kaladins arrival: Kaladins leadership kicks in and his arrival may spur some of this I imagine he'll get them building stormwagons or houses designed to defend from both sides.
Or the parshmen attack soon after and he fights them off then everyone goes gaga for the shardbearer without realising just who he is until he finally catches one of his parents alone.
I like the thought of Kaladin later rocking up to Kholinar and finding some darkeyes in charge and making as big a ham of it as the lighteyes, perhaps even bigger. I also like the idea that Jasnah or some other force rocked up and saved hearthstone before his arrival and he ends up trying to lead and stepping on peoples toes and this leads to an oath based around respecting other leaders, or following others when they are leading.
