Some suggestions: note the contrast with other responses to Jesus in the context. You may also need to focus less on intervening material, since the betrayal takes place over different parts of the chapter. As part of context, pay attention to earlier scenes that refer to the coming betrayal, and the conclusion of Judas in ch. 27. There are some important allusions to the OT in the passage to explore, and Jesus talks about the OT as well. Because of course the death and betrayal of Jesus are central here, you may find fewer observations to make about discipleship, but the other two theological categories will be fruitful.
