IIRC this post was linked to what you are talking about & there was some sort of helicopter crash above their estate taking out some family member around that time.

Though Q has also said multiple meanings exist & this could be a reminder if the Rothschild fam is involved in stolen elections?

That would require much more digging that I have time for currently to figure out if there is any validity to my speculation.

edit: Also I believe this is when Anons were able to confirm that Q team & government's were able to & did listen to citizens via their smart devices. Though I might be recalling that incorrectly.
