Amidst all the birthday celebration scenario and entertainment, something that Flower hadn't really thought of before promptly emerged her head, excessively. She didn't know why she always seemed to forget about it whenever she woke. And as a pet owner it should be the first thing that should always overwhelm her mind every morning.
Flower was currently pondering about Snow and his whereabouts, she knew that she was a careless pet owner, always forgetting about Snow every now and then.
Even if not for Horatio's interference, then Snow would've starved a lot this day, Horatio was always the one in charge of Snow this past few days, and Flower was certain and could also percept unhinderingly that Horatio was a really good pet owner than her. This made her question her authority and right as a loving pet owner.
