The global corona is more like an (upside-down?) bowlful of jelly than it is
like a house of cards.
Here we see a flare/CME (red/green) launching an EUV wave that excites a
"winking filament" some
distance away.
The CME core (blue) presumably contains one filament, but the remote
cavity (purple strapping field)
supports another (red/black) which can then bob up and down.
