It Is Written
When a man is left behind in the desert Sherif tells Lawrence to leave him as his death is written. Lawrence rejects this ideology and goes back for him. Lawrence tells him that nothing is written and Sherif rejects this. Ironically Lawrence returns with the man to everyone's surprise and changes the viewpoint of the men he is with as it empowers them to know that there is more they can do for their fellow man.
Exhibitionist
In London a man says that Lawrence was an exhibitionist to which another man demands he take his statement back for he knew Lawrence to be a good man. Ironically when asked if he knew Lawrence the man defending him says he's merely shook his hand and nothing more. Thus he's defending Lawrence on the basis of what he believed about him not what he experienced with him.
Matchstick
Lawrence puts out a matchstick with his fingertips to which he shows great joy in doing so. Ironically another man tries the same and burns himself. Lawrence tells him that it always hurts...it's just not minding the pain that allows him to continue to do it.
The Well
Tafas leads Lawrence to a well in order to drink in the desert. Tafas is shot by Sherif for doing so because Tafas is not allowed to drink from this well. Ironically Tafas knew that if he drank from this well that he could be killed as he is part of a different tribe than Sherif, yet he still chose to do so.
9 Centuries Ago
Prince Feisal tells Lawrence how his people had two miles of lit streets when London was still a village. The Prince is speaking of the innovation and power that his people have held in their hands and now the English seek to rule over them. The irony though is that all of this innovation and power was 9 centuries earlier and they do not have it any more.
