They did call it an "unexpected response’’ to the surgery. Since he’s eating and not in any apparent pain, that would seem to rule out colic. With a compound fracture, infection would be, well, not anticipated, but definitely on the list of things to watch out for.
The only mention I’ve seen of the fracture being open is in the initial report in the BH. Every other article references a condylar fracture with suspensory damage. That doesn’t mean the initial report was wrong, just that it hasn’t been brought up again.
I wonder if he’s having neurological problems…fervently hoping that isn’t the case.
