There's been a bit of a gap between realising some people were gone and Mami - and Mami's friend's - arrival to the blue team. So while Madoka has gotten over the initial shock at that point thanks to having had a little while to process it and to go out and try to look for Maru with some people, it hasn't done much about the sadness yet. About the realisation that so many important people to her really are gone. Temporarily, for now, but perhaps permanently later.

But when she spots a very familiar yellow colour standing out against the background of everything around them being so white, Madoka is quick to run over towards the figure. Of course-- even though some people are gone, and it hurts a lot, at least she's not entirely alone.

"M.. Mami-san..!" She shouts as she runs towards the other girl.
