I remember this episode
Madoka clearly remembers the previous timeline, although she's not (yet?) aware that she is doing so. I was thinking that the other characters remember too, but not directly, but only indirectly, in the increased seriousness with which they take their roles as MGs. This would be a memory that does not rise even to the level of a deja vu: it would be more like the way Freud talks about the unconscious structuring the conscious mind, unbeknown to the conscious mind itself.
No doubt the slice-of-life series will feature Madoka visiting her therapist weekly.
Just kidding, that's not going to happen. Sorry to scare everybody!!!
