She's mad at me again

Helen got in trouble this afternoon. she won't stay out of my room. She empties out my nightstand drawers, hides things of Benny's and mine. All in all, she's a sneaky little shit. So when I took Ruthie and the little boy I watch outside, Helen has to sit on the steps. No playing. I couldn't see her from every spot in the front of the house, but I 'd go to check on her every once in a while. The last time I checked I found this:
She was fully clothed when we came outside. I hope she grows out of this before junior high.
