food for thoughts: it is pretty unlikely Honerva was the only one who was researching the comet crash site on Daibazaal but Coran did not mention anyone else, just her. Is he an unreliable narrator? Did something happen to those researchers ? Or do you believe she WAS the only one at the site?
We do see other researchers, but I suspect the focus on Honerva was that she was chosen to head the project. After all, to understand some completely unknown hole in reality, you’d want the “Best alchemist on Altea” running the show and calling the shots, right? Especially with how all of the other researchers appear to be galra, it’d suggest that Honerva traveled to Altea to personally take that position.
People have pointed out that someone with Honerva’s skintone and hair is in the shots of the forging of the Black Lion in s2e7- look between the two pieces of comet.
She’s easier to spot here because she’s in the exact spot we see her in for most of the flashback (and, in fact, most of the series): right beside Zarkon.
Coran, Alfor, and an Altean with curly pale blue hair are also present in both pictures, and in the second picture we have a mixed crowd of Alteans and Galra. This means Honerva also helped with creating the Black Lion, but, it also could imply that this was the team dealing with the rift in general- suggesting more of a joint effort than just Honerva, eventually a citizen of Daibazaal herself, leading a team of galra.
We don’t see any of those other researchers when Alfor visits and Honerva is starting to look distinctly Haggar, I have to wonder if towards the end of her life she was doing her research alone, but initially it was much more of a team effort.
I’d assume if nothing else Alfor would withdraw his support for the project and whichever of his people were involved after he made his criticisms of it clear.
But both Coran’s narrative and the Black Lion’s would seem to suggest multiple researchers, just Honerva leading the study of the rift itself, and Alfor leading the construction of the Lions.
