SO any idea if it's
A. someone who didn't know Shalla Bol but only saw her Silver Surfer form and assumed that she's the one (edit: I finally found the one I was talking about, which is Star Glow. Wonder if it was meant to be plot twist and homage to that what if.)
OR
B. trying to lean more on recent storyline (but without origin story in continuity, just like MCU Spiderman taking more from Miles Morales). Like only one time she became Silver Surfer was from either What If or Mark Allred's run.
