I Know This Much Is True question

When Prosperine moved in with the old hunchback woman she had turned 1 rabbit into 2 for the manin the market that would complain about her prices. That was when she believed the old woman to have magic. I think after that Prosperine began to feel close to the old woman. When Dom turned the 2 rabbits into one I saw it as bringing peace to her and knowing that she was going to join the old woman in Heaven. That was my take on it anyways...
