Okay, so from your posts, I have realized that Emily is Charlie's twin and a radioapple kiddo. Before now, I assumed that Emily had a connection to the heart of Eden somehow, and I STILL think she does because I also don't think it's a coincidence that the heart of eden disappeared around the time that lucifer was banished. I know it's more likely that was happened to eden probably has to do with roo alone (although idk what that is cause I'm still iffy on what her place is in hazbin lore) and not lucifer, but I do think it would be really poetic if the heart of hell and the heart of eden, two reflections of each other, ended up exchanging parts of their souls in the fall and becoming entwined as the first soulmates. Like, life and judgement being intwined, and that it was life itself that gave freewill to humanity? THE POETRY. Anyways, I know it's not likely, and I won't be disappointed when it turns out not to be the case, but this is my theory for now.
