Curious indeed, and it doesn't go unnoticed, because Irene does a similar thing- act. Her performance is more an exaggeration of the truth than a whole new persona, but it's still a performance.

"Love to," Irene says, straightening up and then settling into the seat, her movements fluid but poised. "I'm Irene," she says by way of introduction, almost making it sound as if she were paying herself a compliment, though she's being friendly rather than haughty. "And that's a marvellous name."

'Ilde Decima'- well, it is.
