New OP is a lot "duller" in colors.
Madoka HENSHIN scene has the runes flying around in alphabetical order.
More walls are around when Madoka is running.
Madoka runs faster.
There's a building.
More fences. Madoka appears during the fence scene.
The end shot seems a lot further away.
GIANT PICTURES ON OP COMPARISONS
Edit: I also thought Mami was shooting the witch from inside, but then you have to realize she got her head bit off and lost her mahou shoujo uniform after. ;_;
Next I heard was Homura made a bunch of explosive clones that Charlotte/witch ate and exploded from inside.
BUT THEN I heard that the doll next to Charlotte is the REAL Charlotte, which Homura landed on before it exploded.
I don't know.
