Original Commentary
I had been working on a week-long sequence involving Robert talking to Brisbane, explaining that he and Jane had plans, and Brisbane suggesting that Jane come over. This is Isabel's idea, to deal with the issue Alexander-the-Great* style. She snuck in already. -Terrence

*At a temple in Gordius, there was a large, complex knot. Whoever undid it, it was said, would rule the world. Alexander the Great went and cut it in half with a sword.

Modern Commentary
Better that Robert brings his girlfriend over than just stay home - Terrence
