It isn’t an absence seizure because she didn’t stare into space like a zombie for a bit, and it can’t be a petit mall because she didn’t fall or lose consciousness. But it was a series of myoclonic jerks, and I truly would believe a seizure, and a recurring one I’d guess because her handlers seemed to be familiar with it.
Have you seen the series `Boss’ with Kelsey Grammar as mayor Chicago?
His character learns that he suffers from some grave, deteriorating physical condition and tries to cope.
It looks to me like Shrillary is doing something similar.
I only play a doctor on FR, but there’s something going on it that clip beyond `laughing it off’.
