In one scene, the boyfriend of the girl he's wooing discovers what he's been up to and proceeds to beat the crud out of him. But, because the woman he loved asked Ewan's character to please don't hurt him, he doesn't even fight back. Now that is love.
After the man is done beating him up, Ewan's character, covered in bruises and still bloody, smiles at her so. Sweetly. This troper honestly didn't know if she wanted to kiss him or rough him up some more.
After spending a long time away from his lover, James Joyce starts sending her dirty letters. The scene in which he reads several of them outloud while touching himself was... Very interesting *fans self*
The scene after he defeats Anakin. Palpatine has taken over the Republic, most Jedi Knights have been killed, he'll have to go into hiding and, what's worse, his own Padawan has betrayed him. There was such raw pain in his face as he saw Anakin burn. It's a powerful scene, and Ewan sells it perfectly.
