Tommen plays with his cat in small hiding spaces. He doesn't want Joffery to make jabs at him any longer, and Cella is no longer here to defend him.
Mother would disprove of him still playing with animals and tell him he is almost a man grown.
So he hides with Princess Vasilisa and brings her milk and fish, because Princess Vasilisa is always loving towards him.
Princess Vasilisa licks his hand while she's grooming herself, and Tommen smiles. She is such a lovely cat.
One day as he goes to the place he keeps Vasilisa, he sees a skirt disappearing around the corner.
Fear flows through his little body and he rushes to his cat. Mother will be so displeased.
But it isn't Mother.
Sansa looks to him with scared eyes, hand outstretched and Vasilisa moving forward to nuzzle it.
He smiles, then joins her, petting Vasilisa's back.
After a while she smiles too.
Together, they sit in silence and pet lovely Princess Vasilisa, who purrs at the affection.
