They visit Langdon's friend, Sir Leigh Teabing, a Holy Grail expert. Teabing claims the Grail is not a cup but instead is Mary Magdalene. He says she was not a prostitute but the wife of Jesus Christ. Teabing argues that Mary was pregnant during His crucifixion, and the Priory formed to protect their descendants. The Opus Dei have been trying to destroy the Grail to preserve the credibility of the Vatican. Later, Silas breaks into Teabing's house, but Teabing, who uses crutches, uses one to disable him. The group escapes to London via Teabing's private plane, along with his butler, Remy Jean. Their interpretation of a clue hidden in the cryptex box leads them to the Temple Church, where they find nothing. Remy, who claims to be the Teacher, frees Silas. Remy takes Teabing hostage, dumping him in the car trunk, and taking Silas to hide out in an Opus Dei safe house. Teabing, who is revealed as the Teacher, later poisons Remy and sends the police after Silas. Police shoot Silas after accidentally wounding Aringarosa, who is promptly arrested by Fache, who resents being used to hunt Langdon.
