"I should certainly hope not as often," he remarks somewhat fearfully, and that's presumably all he'll say about the eating needs of bats. He does, naturally, expect the trip to the battle to take days in itself. If they take their own route to gather there, and then enter in for a fight....well, that would be perfect wouldn't it?

"Oh...I'd hardly be doing anything toward the effort that way though would I? Rather more like a tick, or perhaps a leech by that point..."

He seems rather stuck on this doesn't he! (He'll break eventually, no doubt.)
