When I picture Miss Featherfall and the Iron Admiral as a couple I get the most delightful image of a grandmotherly woman on the arm of a straight, cold, hard man. the kind of man people would say has a heart of stone. I like them as a couple because, to me, she saves him from being inhuman. The fact that he likes her, evidenced by his need to have her with him at tea time, shows he has a heart (or had one till he lost it to the obviously adorable Miss Feartherfall). I imagine them as old friends, that the Admiral has a dark sense of humor, and that Miss Featherfall has often had to rearrange her plans to accommodate him.
Maybe i'm the one with the dark sense of humor because I thought it a charming love story.
