Goddess Patty's last batch of videos, where she was all but immobile, barely managing to get from her bed to the bathroom. (If she was faking her exhaustion in those she deserves a posthumous academy award). Also the whole "I'm doing this for you guys" thing, where the implication was that she wasn't really into it anymore. She later made that documentary where she blamed her bf/feeder for manipulating her (a la Gina).
Not to mention she was clearly stoned out of her mind t/o all of it, the discoloration and f'ed up skin texture on her lower belly, the stain on her couch under her crotch, and that she was pretty much naked in every video, not bothering to get dressed anymore.
I was addicted to her (and I'm twisted in general) so I stayed subbed but I figured I was watching a slow-motion, multi-part snuff film. Was perversely glad when she retired and left her bf, even though she was smaller and looked 10 years older.
