If there were any problems in rallying the Knights of the Round Table, both King Arthur and Hewitt would only think that the issue might lie with Mordred.
That's why he deliberately approached this Rebel Knight - the one most likely to betray King Arthur among the entire Round Table.
Although as long as King Arthur fully recovers, the clever Mordred would have surprising loyalty, even willing to risk his life for the king, but now the situation was a bit delicate.
Arthur's physical condition was terrible, mainly due to the severe damage she suffered before awakening, as well as the side effects of waking up prematurely.
If Hewitt had not awakened her, she would have naturally awakened when her body instinctively accumulated enough energy.
But Hewitt still woke her up and put her at risk. To this, Hewitt was not bothered; his standard for such matters was simple.
