How It All Goes Down
- Langdon's got it figured out: he's holding the Priory keystone.
- …and according to Priory lore, the keystone is an encoded map that reveals the hiding place of the Grail.
- He gives an incredulous Sophie a lesson on the legend of the keystone.
- Basically, the location of the Grail was passed down via word of mouth for centuries, until the last few decades when Priory policy changed.
- Now it's never spoken aloud, but revealed via a series of tests. So, if you can open the keystone, then you deserve to know where the Grail is.
- Sophie reveals that she thinks her grandfather was the Grand Master of the Priory. Langdon thinks it over, and realizes it might just make sense.
- If that were the case, though, then he's flummoxed as to why the Grand Master would have requested a meeting with him, and why did he give the keystone to his granddaughter instead of one of the other three sénéchaux?
- Langdon doesn't have time to figure it out. The truck comes to a stop earlier than expected.
- When Vernet opens the doors, he's holding them at gunpoint.
