Yeah... it's moments like this that I feel like help show Anna is a bit of a child, too. But, at the same time, she's a clever child. And very forward in her actions. Feeding him crumbs she literally showered on his own lap is one of those 'outstanding moves' that's just so very on-brand for Anna.
Also, is that second page the preview for the next main chapter? Some shocked or amused expressions, except Serina, she seems kinda done, but that's pretty standard for her, I suppose.
