“I know what is the matter with me. It is a coolie disease from
Sumatra–a thing that the Dutch know more about than we, though they
have made little of it up to date. One thing only is certain. It is
infallibly deadly, and it is horribly contagious.”
So like i don’t mind Prince Lance being Allura’s brother
but like imagine if he was from another kingdom on the planet. A rival kingdom they have high tensions with so set up an arranged marriage between the two that neither was happy with? (Lance enjoying being free to flirt with Allura without it actually meaning anything, without Allura pretending to giggle while glaring holes into his head)
A kingdom they had a good trades relationship with?
A smaller kingdom that Alfor’s thought was ‘beneath them’ and ‘needed enlightment and to be taught proper civil ways’
A kingdom not so happy with Alfor having a powerful weapon like Voltron and demanding assurances it won’t be used against them (causing the arranged marriage, or maybe an arranged marriage to Lotor since his father in the head of Voltron, or maybe causing Lance to become the blue paladin).
i just really love the idea of Lance being altean royalty with a more interesting connection to Allura than family, you know?
