Wolfy seems to run the joint.
Whenever someone challenges her she crushes them or cries her rival into submission. She owns the 'correct usage of fat', no-one will challenge her on her cockiness about reaching the final, Hazel never defends Dan when Wolfy slags him off, cried so that Jemima almost had to take the least hygenic tag, she lies and gets away with it (bar Dan's interrogation), even Gina didn't push Wolfy hard about not following through on Hazel's VT. When someone dares to challenge her e.g. Dan he has hell to pay and she manages to pull out the bully tag or no-one understands me as I am so unique.
She seems to have a lot of say in the food e.g. rowing with Dan over the correct use of sausages, and demanded Dexter explain himself when he admitted he was going to nominate her. It's as if she is entitled to be 'above being nominated'.
Wolfy runs that house.
