I would have thought an ice bath would reduce the pain from his calf condition but not necessarily the effects of his swollen head.
So he’s in pain and suffering from already compressed blood flow to his calf’s and Norths response is to throw him in an ice bath and reduce it even further? Not the best logic there and probably a reason he was frustrated.
Literally the last thing you would want to do given his diagnosis is actually reduce the blood flow even further by putting him in ice.
