Ben behaving like kind of a douche
Emily is a very nice, very young stew and he should not be making decisions in the galley based on her opinions if they contradict Kate's.
I get it that they are in the first full flush, but that doesn't mean he is allowed to jettison professional behavior and tell Kate when she complains about E's b-day flowers being in the way that he wanted "to put the flowers where Emily could enjoy them." He sounded like a real douche bag.
