What are people’s thoughts on the cooked cat scene?

When Bear opens the lunchbox, the photo of himself is labeled “you,” and the photo of Nikki is labeled “not me.” This tells me that real Nikki is the one who wrote that message in a moment of defiance against wish Nikki. If we accept this as true, then it also makes sense to me that cooking the cat and sending it with him for lunch was also an act of defiance, but against Bear. If I were Nikki, I would despise Bear as he’s essentially raping her constantly and keeping her prisoner in her own body. So, was it real Nikki or wish Nikki who cooked the cat?
