Julian took offense to a comment that the vet made, he said to Julian that they were probably the problem. Luna did not trust them to let Lily sleep alone. However, Julian knew deep down that there was something else. He could not be the problem, could he? For a while, they decided to observe Luna together with Lily.
Lily seemed to love the cat, and Luna definitely loved Lily, but they could not say goodbye to Luna because she was overprotective. The problem was every time that Julian would bring Lily to bed or Lily fell asleep Luna would be at her side. Julian just accepted the situation, until one day Eve called that she was bitten by Luna. This gave Julian a sudden realization.
