And already she is torn between two cultures. Her ambivalence and even distress at the idea of killing Sinclair, her doubts about the Grey Council, her (I think it's implied) inward comparison of Franklin's involvement in the war with her own culpability, all play to the inherent dichotomy that lies behind the show.

Also the contrast between Delenn's statements to Sinclair that she is his friend, that no one here will hurt him; to Sinclair's declaration that it was ages before he could look at a Minbari without wanting to choke the life out of them, and his recalled torture at her hands. Lots of good stuff there.
