I will say that after the canon series 3 (and the model change) up until the end of series 6, the characterisations of the mains and recurring supporting characters don’t really change too much. Obviously plots continue that have impacts on later stories so it’s not like they can go in any order, but the characters don’t change all that much. The main trio and Padmé are especially static after that point I feel.
I think this is accurate.
