You're Okay And So Am I

A nightmare comes to the queen at night, one she's had plenty of times. And one her sister always helps her with. The two are together again and they act like sisters should. But with a visit and departure of Weselton, Elsa shows a worrying part of herself not even her sister has seen before. Is it okay to just pass it as nothing?(incest at one point, so rating/genre might change)
