I never read it as incompetence, I figured she would hardly be the only person ever to be lost in an unfamiliar, dangerous, hostile area. Nevertheless this is a way more fun option to consider. After all she was always hanging around by waterfalls and stuff, and Goldberry isn't that unique. At least if you go by the poems she is just one of the daughters of the river woman. So why not...

Still, not exactly what I thought I was going to write for my first femslash, or actually, first lurve scene ever, hahaha. Seduction by possessed erotic water plants. *headache* Obviously can't do romance right, or at even with any semblance to normality. xD
