Idk what evidence there is for whatever light world object Ralsei is or if there is evidence proving hes not an object but until its spelled out im always gonna think he is some of Toriels fur on Kris' sweater.
Not even because how he looks! But he acts as our dark world tutorial guy like how she does and cuz their personalitys are kinda similar.
You could argue that he could be some of Azzy's fur or some of Asgores fur but my money is on Toriel!
