To make them a grave would be giving up. To keep that promise would be to accept their erasure. Narinder has broken godhood and rules of existence once, twice, already. He simply just has to do it again
anyways this is me now that someone has pointed this out btw:
Sara, you have no clue how much this has been going around in my head.
The second i saw the crowns side eye when Finor asked about the grave I KNEW this was connected to the side eye the crown gave narinder in the other comic!
I am so unwell about a possible conversation where Lambert revives (hello happy ending I need you aaaaaaaaaa) and they realize that Narinder broke his promis to them. And they probably get upset (because, if I’m correct about where i THINK their death will happen, they will not yet be aware about their own importance towards narinder) because he didn’t care enough and they confront him about it. And narinder (still freshly traumatized) would have to explain, maybe even have a small breakdown about how he just couldn’t do it.
And Lambert would realize that him not being able to accept their death is a way larger admission of his affection then any monument of mourning could ever be.
YOU. you get it
For a short time, Lambert believing this is the final sign that they hardly mean anything to him, then Narinder is gripping them, holding them close and shaking trying to explain that he did not have the will to accept losing them and would rather face the consequences of breaking universal rules again and again than to bury his heart into the ground
