what happned to the image fallowing this?

I don't get what happened there >.<

Looks like Alice called the wrong name

I love the last panel.
I guess this is post-Marisa(long life tragedy).Alice tried to move on with Yuuka but she can't since she still can't forget Marisa (maybe she think of Yuuka as Marisa's shadow,or as a rebound), hence the slap and Yuuka asking if it opens her eyes.
