Saoinji, in a rare moment of insight, also contributes that being abused by your loved one is preferable to being separated from them. Although he is twisted, Saoinji apparently does actually like Anthy which is the first positive sign for his character that we've seen.
I can't say I have much to say about this episode except that it illustrates how people's perceptions shape the world. Nanami believes that someone is trying to kill her so she reads meaning into the conversations of others, Mitsuru wants to be a hero so creates dangerous situations to become one and Saoinji believes himself in love with Anthy.
