This one would be based on Luka, but in Alien Stage, after winning the 49th Alien Stage, he was crowned the 'best singer' in all of Alien stage, even earning the highest points on Alien Stage history in Round 4. This could also be another reason why that specific round wasn't shown. (Though it would have been cool to see how high the scores got)

But, this would also point out the reason why Luka has his health issues. I heard this one the Wiki page on luka from the comments, but could selective breeding be the cause to this?

Maybe the aliens were trying to breed the best singer they could produce to compete in Alien stage, thus Luka, and they absolutely nailed it due to winning the 49th Alien Stage, and even the 50th, (Well, in the alien's perspective, since Hyuna and Mizi were featured guests) and could even lead to his health issues, as seen by dogs who have been specifically been bred to look or act in a certain way.

NEXT THEORY:

Hyuna is not just a 'girlboss'

We all know we don't know much about Hyuna, but with the recent comics, i think it may have been seen she is hiding some sort of personality behind her upbeat and energetic facade.

It was also shown that Hyuna had grown to like Mizi, having a closer relationshi than with Dewey and Isaac. (Though this may not be real, it could just be that she had simply opened up faster to Mizi than the rest of her pals in the resistance)

I think it's beacuse she sees herself in Mizi, loosing someone so precious to them (Hyun Woo for Hyuna and Sua for Mizi) So she intentionally gets closer to her because she chose to fight along side Mizi- to fight for their freedom against the aliens.

Im not sure if this would necessarily be true, because ik she's been friends with Dewey and Isaac longer than Mizi has, but I think it would be interesting since Mizi is the only other female resistance member other than Hyuna that we've seen so far, so it would be interesting to see that Hyuna would be more closer to Mizi.

NEXT THEORY:

When Till was breathing his 'last' (HE'S ALIVE, TRUST) Mizi was looking down at him with tears in her eyes, which could have possibly reminded Till of his mother when she was taken away from him. It could also be another reason his hand went to hold Mizi's. Not only to hold the person he cherished, but also the figure of his mother for the last time.

NEXT THEORY: (Connected to the last one.)

This is sticking with the trend of Till's mother, but the reason why he could have fallen for Mizi was because he saw his mother in her. I don't really know how to explain how Till saw Io in Mizi, but then again, it could be a reason he couldn't express his feelings to her.

He was scared of forming a really close bond with the closest people around him, (Mizi and Ivan) because he was scared of loosing them like he did with his mother, the reason why he couldn't reciprocrate Ivan's feelings and express his love for Mizi.

ANOTHER THEORY CONNECTED TO THIS ONE:

This could also be a reason why he didn't have many other friends. Of course, he was a part of the main cast, but this would be a reason why he was never shown to have interacted with the other kids as much as he did with Mizi or Ivan.

But do you guys remember the recorder that was shown in multiple official arts? I'm not sure who gave this to him, nor how he got it, but I don't think any of the main cast had given it to him.

Due to the lack of relationships he has with others, this could be a way of building some sort of connection without having to interact, it was a simple gift, yet he cherishes it as shown in official arts.

(Just a few of them bc why not)
