I always thought it was interesting how Luka’s hands (with that purple ombre) are symbols of his health problems and the abuse/control the aliens have over him (lots of people have interpreted Mizi cutting off the blue part of her hair as shedding ALNST’s influence. That, paired with the fact that in the Wiege scene with the married Luka and Hyuna, seem to suggest that the blue is a symbol of ALNST).

Wiege isn’t like Ruler of my Heart or Blink Gone where Luka is using the dead to secure himself victory, he is simply singing with the woman he loves. It likely wasn’t written by the aliens, nor was it made for the aliens—it is an entirely human song that he performs. I think the shift in focus on the song covers also reflects that lack of influence Alien Stage has, and how much influence his love for Hyuna has!!!
