That's interesting - while I don't object on principle to reacting like that to reader comments, and hadn't already written ch. 32, I don't have a memory of consciously choosing to include killer whales because of your question. In my head it looked like I was going, "Well, they're on an island, Bella would rather not hunt close to humans, somebody would probably be annoyed with me if they ate dolphins... what's the range on killer whales? Oh, those things are all over the place, that's what's for dinner." But of course I read your question, and you probably primed me.
