Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Finding Judas
Some time after the surgery is stopped, Chase enters the doctors lounge, visibly stressed. As he is preparing a sandwich, he and Wilson talk. Chase tells Wilson that he cannot stand the situation anymore, and that he's become impatient with waiting for House's approval and abruptly leaves the room. The door to Tritter's makeshift office is seen opening, and Tritter has a surprised look on his face when he sees who has come to talk to him. We then see it is Wilson, and he says "I'm gonna need thirty pieces of silver", a reference to the price for which Judas betrayed Jesus.
