Delenn and the Soul Hunter outline their differing beliefs
This episode is the most we see of any Soul Hunter in the series proper, and I love W. Morgan Sheppard's performance so much. Granted, he's an atypical representative, but it's a nice window into how solemnly his race approaches what it sees as its duty... and, for just a moment, Delenn sets aside her fury as she processes what all this means to him. (Of course, she shuts right down the moment he names her.)
