An analisis on the symbolism of this shot and what it means for Jayce and Viktor

(this does not contain any le*ks, only material that has been officially released so far.)
But first to understand what this shot means, his connection to the new magic and how this relates to his relationship with Viktor, we need to look at what his bracelet represents.
He got the crystal for his bracelet by a mage who saved him from an impossible situation, this implanted in him a lifelong obsession with the idea that if he could give this tool to people, he could greatly improve the lives of many.

But since he knew they would not allow experiments like this in Piltover in normal circumstances, he needed to do it in secret. This is what at that moment the bracelet represents.
His conviction is so strong, this goal is so important to him that he made the reminder of that fateful encounter something that he can not just carry, but wear it on himself everywhere he goes. However it is hidden, the same way he needs to hide his research.

But then he is found out, his research is going to be destroyed, and he loses all hope in completing his dream. So he takes the bracelet off, as a symbol on how he is given up. But then Viktor comes into the picture.

He gives his bracelet back and with it his hope for his dream, it's no longer something he has to burden himself alone, it's not just Jayces dream anymore, and so he declares: our hextech dream.

And this gesture and this declaration changes the meaning behind this bracelet, it's not just a symbol of his dream anymore, it's now a symbol of their shared dream of helping people and in turn their relationship and partnership.

This thematic connection is later emphasized when he complains about being useless in the face of Viktors illness and his frustration about not being able to develop the technology he wants to and he reflexively tuches it.

And after he no longer needs to hide it and he can fully pursue his dream, he puts it on proud display, he turns the crystal upside down and even has clothing that lets his bracelet show, he is proud of they work and he shows that off.

But in the shot we got for the crystal to embed itself in that way, he needed to turn the bracelet upside down. And why would he do that? Well, he would need to be so disillusioned with their dream, so ashamed of letting Viktor down that he doesn't even want to be reminded of it.

I dont think it's a controversial thing to say that Jayce will have a chance to destroy the core and he won't, which initially Viktor will be mad about, but later allow Viktor to do his shenanigans with it. Thematically that would make sense.
But the bracelet isn't just worn in a different way, that would be reversible, the crystal is literally burned into him with a crack in the middle. It is irreversible. What does that symbolize?
Easy, they didn't just lost they dream,
THEY DREAM IS DEAD

The crystal is no longer a symbol of his hopes and dreams and a wonderful relationship, It is a symbol of his failure to do good with hextech, broken promises, and letting down his closest friend.
it is grotesquely melted into him forever, a reminder how he cannot escape the reality he helped create. Giving hextech to people is no longer a dream, it is real and it's a nightmare, he didn't improve anyone's lives who needed it, he made weapons to oppress.

And the gem is cracked in the middle, mirroring his broken relationship with Viktor, the man he let down over and over again, he wasn't there when he needed him, he went against his will and made weapons, and he failed to fulfill his promise to him.

Since we saw Viktor will gain the ability the transform people, I would teorise that he will be the one who will melt the crystal and metal into him in a heated argument. (tho his powers are distinctly purple)

It is not something he wants to remember, but it is something he will have to carry for the rest of his life.
And now Viktors mind is twisted, he was not strong enough to destroy the core when his mind was still intact and now Viktor commits horrific acts in the name of trying to do ultimately good.
And so the bracelet is not just a reminder of his failure, but also a reminder of the promise he will have to fulfill one way or another.
