Unless Elliot's victim comes out and illuminates the way, we are left to speculation and I say this is a good thing.
The entire ordeal could just be Elliot's porn fantasy. It could be his humiliation fetish combined with his coomer brained self-insertion of some disgusting furry/bestiality porn he's consumed.
I think what happened was, he invited a female colleague over, someone that unfortunately politically aligns with Elliot or trusted the rapist too much, and they drank a little. Elliot may or may not have spiked her drinks, and after some psychopathic wrangling, she was persuaded into some kind of disgusting play. Plenty of ugly freaks get laid. Elliot could be her manager, and she has cynophobia (scared of dogs). They got on and Elliot's dog appeared, scaring the shit out of her, she retracted consent but Elliot went ahead anyway because he's a dude that's stronger, or the disgusting play may have been her bondage/handcuffs.
I refuse to believe the dog hair story unless it's a severe allergy. Elliot is definitely the kind of psychopath to use his position and power to get some natal woman under his manhands. The so called consent accident implies retracted consent at the very least, and when someone doesn't consent to sex, what do we call it?
Rape.
Kill yourself Elliot you misogynist.
