Watched "One Night Stand" from Grimm. Three naiad sisters in their normal, human form befriend two teen-age boys who are out fishing. They end up swimming in the water, but the two boys are mysteriously pulled under by strange creatures. The youngest sister rescues one of the boys whom she has a crush on. Nick and Hank investigate the drowning of the other boy, and in the course of events arrest two of the sisters and their father. As it turns out, the boys were pulled underwater by the two, jealous, male naiads who were betrothed to them according to their tradition.

Somewhat a deconstruction of the dramatic situation in _The Little Mermaid_, which, ironically, is not by the Brothers Grimm but by Hans Christian Andersen.

Rosalee moves in with Monroe.
