Just got off the phone to Adrian -- Neal (mr_snips) is responding well to treatment, his blood pressure's back down, but they'll be keeping him while they try to figure out what happened, as they don't have a clear cause yet -- it doesn't look like smokers' high blood pressure -- trust him to be mysterious! We're running over some necessities this afternoon to keep him entertained.
Gruesome details, as promised! Blood vessels burst in the back of his eyes, temporarily occluding his vision. That's getting better, too, but it takes a while to clear, so he's getting Adrian to bulk-reply to your texts rather than working through them himself.
