So, this is Blurryface and Reflection's past, they were kinda like siblings, not rly tho, but Reflection was VERY agressive and rude towards her bro, until she left him to die alone, after doing those things she cursed herself into a black void, hoping that she wouldn't do any harm to anyone anymore, but she's harmless now, even caring and very soft-hearted, she's still very scarred by her past and dreamed all the bad things she did weren't real or smth like that :P
