When Ghislane's case was happening, right in sync with milestones, there were many instances of Asteroid news. Infact the asteroid news used to pour in almost weekly during that time.

The first clue was when the asteroid size of Eiffel tower in the news. We knew it had to do be comms about France, but what?

Lo behold Ghislane hiding in Paris news.

After that it was on cue. Asteroid the size of Empire State, asteroid that can destroy the eart, etc etc synchronised with Ghislane's trial milestones.

And since then the asteroid news just trickled down to nothing once she was out of the news.
