I've heard that IMAGE_FRIEND Knight became more likely with the new chapter, can someone elaborate why?

I might just start believing IMAGE_FRIEND Knight over DessKnight because wtf is he even doing if he didn't appear in the Chapter 5, the field of PINK and GOLD, the chapter of the flowers (that have ROOTS), and the chapter where Asgore investigates the Dessappearance if we consider IMAGE_FRIEND the Pointed Tail
