What this podcast has taught me is that there is no one person, there is no written-in-the-stars destiny, most of the time (sorry). Sure, there is luck in Aaron and Rachel’s Tube meet-cute in episode one — both being on that same Tube carriage, a seat opposite Rachel becoming available, Aaron happening to have a spare business card in his pocket — but there’s a whole lot of choice in it, too: Rachel following Aaron onto that Tube carriage, Aaron taking that seat, Rachel following up on that business card. The transient nature of public transport just forced them to be braver and make those choices more quickly than they might have done in another situation; than many of us might do every day, when a sexy stranger sits next to us on the Victoria Line.
