At first I started to get choked up when I saw this. Viral's dream always had that effect on me, and Kyouko is a very appropriate fit for that role.
Then I saw Sayaka.
I thought "Eh? What's she doing here? isn't Mami the one who's supposed to break everyone out of the dream?", but then it hit me: Sayaka is Kyouko's wife in this dream.
