Spoiler:

I'm not quite sure what you mean by Matsuri not having any recollection since she does seem to remember the past, but the answer to your second question is in the episode. Aono killed herself because she didn't want to live in a world without Yorito (at least that's what she said when Matsuri brought her back). It's implied that Yorito is something much more than just a younger brother to her, even though she insists on calling him a younger brother when she and Matsuri first meet again.
