This is horribly rough and sketched but Nessie Lore post!
Because Nessie and her twin El share the same body only one person can be in control at a time.
Normally when Nessie sleeps her body is easier to take control of and that's when El can walk around and do what she pleases.
However, when Nessie is awake, it's a lot harder. El is forced to exist solely on a small patch of beach floating over an abyss, which they had previously died on before they merged.
El can really only listen and watch small moments through a black haze.
Nessie has done her best to restrict El from having control of her body & it's taken a toll on their relationship.
Being stranded on a red tiny island for years sucks ass and the two siblings are still working some anger they feel about each other.
