The seagull is the sort of character I obviously enjoy using, who comes into the story in one context, usually in a secondary or background role, and ultimately - after they've been part of the landscape long enough to be pigeon-holed and taken for granted - turns out to be something else. Or perhaps sometimes a seagull is just a seagull.
The stage business with the snacks in the first part of the chapter is, if you can believe, a nod toward Roger Zelazny. Specifically, the wonderful bit at the end of the first short chapter of Lord of Light
, when the first characters on stage have been discussing their grand, world-shaking plot, and then one of them, who is currently incarnated as an ape, leads into the scene-change blackout by requesting a banana.
