Secondly, Kris is the only true knight in the entire game, they are the only character seen utilizing a traditional knight's arsenal while the "Roaring Knight" is much less pronounced as a knight, they use a bat, no shield and seemingly has no armor at least in the traditional sense, the visor is fake and they look more like an eldritch beast when using their full power. The attitudes seem different as well, the Roaring Knight doesn't really seem to be protecting anyone or anything per say while Kris absolutely sticks up for and protects their friends, independent of our influence even though their and the Knight's interests line up to some degree.
Thirdly, the Roaring was likely supposed to happen on a shorter timescale compared to the scenario we find ourselves in Deltarune which is why we're starting to see little holes pop up in multiples aspects of the prophecy. The panel and subsequent room showing "the girl" pasted everywhere is showing us that there are now divergent paths for a prophecy that was supposed to be clear-cut and straightforward, indicating that something has changed, I think the iconography is showing how Noelle will NOW have to be "the girl" to complete the prophecy and it will happen regardless if you take control in weird route or not (hence the panels both with and without hearts). Gerson is also hammering this in during the whole chapter while interacting with you and especially Susie, different interpretations can make a difference in this prophecy. Assuming the player is the Angel foretold in the prophecy also clearly explains why Asriel would ditch town suddenly beyond Dess's disappearance and stash the Goner in the locked door within the castle (Angel wings surrounding the door with a heart), Asriel thinks this might be able to stagger the prophecy indefinitely until he comes back with a solution but instead the prophecy restarts with different characters after Gaster inserts you and you overwrite Kris's soul.
