In The First Continuation, the sick king does not appear to be in the same state of agony as Spicer's depiction. There is no doubt however, that the king is wounded in some way:

There they found a most handsome, white-haired nobleman sitting on a bed; he was certainly not a penitent or an ill-bred man, or a servant or a layabout: his gown alone was worth a hundred marks, and his hat was not made of straw but rich sable covered with Alexandrine silk, and on top of the hat there was a most beautiful circle of gold, full of jaspers and sardonyx and other handsome precious stones, the finest that one cold ever have. His wealth was very great. He was lying on the bed, leaning on his elbow; and it seemed indeed that he could have lived in great happiness, for he would have been a lord of great riches, if his body had not been maimed, rendering him helpless.
