Curate, connect, and discover
Honestly I kind of find the parallels to Alfor to be quite superficial? Like yes, Lance gets the altean broadsword (which, in the end, serves no real purpose), he has a conflicting relationship with Keith/Kuron (who, like you sad, both represent Zarkon in their own way), he loves Allura and eventually gets the same blue altean marks... But then? What was the real reason to make the parallels in the first place? It would make sense if he became New Altea's ruler or Coran's advisor (and thus making a parallel with Keith who is still involved with the Blades and the Galra after the war), or if he inherited Allura's powers, but no, he's a retired and depressed farmer at 20 years old, which makes no sense for his character at all.
I personally believe in the theory that s08 was heavily edited and that a lot of the material involving Lance's character arc was inevitably cut in the end, but still I don't understand what the writers were actually trying to do... And yes, I heard about that cursed "Lance raises baby Allura" concept, thank God they didn't do that.
Not an allurance shipper but always an Allurance defender
But the one thing i can't defend is the writers insisting on the Lance/Alfor parallels specially since they knew (I presume) Allurance was endgame
What was the purpose of that? Why?
Maybe it was for Lauren's cursed idea of bringing Allura back as a baby and have Lance raise her but that honestly makes it like a hundred times worse
