valid point. But based on the assumption that she CAN reach the plug the way she is bound.
If I was the person that tied her, I'd make damn sure she wouldnt be able to reach that plug without either breaking a rib or dislocating an arm.
Which it kinda looks like in the picture.
I mean what kinda dumbass goes through all the shit to set this up just to let her escape unharmed?
Personally, if it was me id gnaw the ropes with my teeth, pull the plug out with my mouth and put my mouth over the drain to breathe.
