Riveting chapter! Took a few days to go through, but it was totally worth it.
The Americas of this timeline will be very different (and dare I say better) than in our timeline. The radical decentralisation of La Plata, the complete abolition of the racial caste system in Colombia and, above all, the dual republic of California where europeans and natives stand as equal will surely influence a much more democratic, equitable and multi ethnic america than in our world.
Being freed so early will also bring valuable time to catch up with their old masters. And who knows, in time maybe the American revolutions will threaten the old order on the old continent itself.
