I thought that when Misha first met Janina he didn't care but then later he kind of liked Janina because he didn't live with them yet then he lived with her and now he has a "sister" of some sort. I think this may represents his knowledge growing slowly. He thinks of angels and happiness and thinks that there is not enough room for both. He still has a lot to learn but he tries to retain all knowledge given.
