"Thought you'd never ask."

This is mostly a joke, because Iris doesn't need to wait to be asked and she knows it - she just likes to wait because he always will ask. Win all round, in her opinion.

She sheds her clothes on the walk from the patio to the pool, dropping them as carelessly as a tree drops its leaves, and hops in with an inarticulate yet expressive pleasure noise.

"That's it. I'm never leaving now."
