Wiege is not about Luka and Hyuna.
I mean, it is. But not fully.
"Wiege" means cradle - it's been told many times. A cradle.. the ANAKT garden, protecting the children, keeping them safe. But a child can't walk out of a cradle.
In Wiege, both Luka and Mizi lost everything they had, except that for Mizi, it took so much time, gradually suffering, building up more and more, while for Luka, it took a second, a blink, and his whole sky dawned on him. He's seen Hyuna, was in her arms.. and then he was left alone, again. Forever, this time.
But this isn't their sorrow alone.
The generations after them will have an unlucky winner that will be left alone as well.
Luka and Hyuna represent the pain of a couple that had the courage to branch out: Hyuna escaped, Luka won. And guess what: they cycled back to the same place. They can never escape: in this Universe, humans cannot escape. Even when they try to find their own Gods, the aliens demolish whatever idea of escapism they had.
And so they have done before this season, and before that.
It's never ending - even when someone feels safe, something intervenes.
Alien Stage never ends well. No matter how plausible it seems for something to go the characters' way, it never happens. Because it's not according to what they want. It's all directed by the creatures that have taken over their free will, rights, and transformed them into pets. I've recently started to be almost unwilling to call them pets; even animals shouldn't be treated the way they are.
In Wiege, little Luka kills his clones, in cold blood, it seems, only then realizing what he's done. The aliens approach him without weapons or hostility: that's what they wanted, isn't it? In my mind, that's how I interpreted it. Him being forced to show his superiority, by killing, essentially, himself. By killing his personality. I think that's the moment where it went wrong for him.
And I think we all know how Sua was treated like a doll, an ornament, how Till was thrown around, beaten up, and then used. Mizi and Ivan are just 2 lucky ones between probably billions of pet humans. In the end, even if Mizi was lucky, her owner still only called her "Creature."
So, Wiege isn't only about the misfortunate couple that withered today: but about every misfortunate couple since the beggining, whose plans were crushed.
In the Modern AU we were shown Luka and Hyuna being engaged, happy, leaning in for a kiss. In the actual Alien Stage, Hyuna was everything Luka had left. Emphasis on had.
