This theory explains how* the playable Nervous remembers Olive (due to him sharing memories with the original Nervous) and how Olive only remembers giving birth to the real Nervous * This whole family has always interested me! Since Olive (with her murderous ways) didn't want to keep twins (which Nervous and "Hidden" were), she gave one to their father, the Grim Reaper. But how would she give him to him without killing another? And she couldn't kill her own son just so his father could take him. So she let it go and kept both. Then, one day Hidden either commited suicide, she made him look at the stars, or it was an accient, but he looked at the stars and got killed. Then, his father took him and they went to the Netherworld together. Olive, then too sad and depressed to do anything else
