During one of the missions, Miles Quaritch accidentally breaks the fingers of his right hand, which is why he has to put on a cast. Over time, he gets used to using his left hand to do simple everyday things, like eating and brushing his teeth, but he does not do it as dexterously as with his working hand, after all, he is right-handed.
While his bones were healing, stubble began to appear on Miles' face. He ignored it for a long time, not daring to go through his own throat with a blade in a trembling hand, but at some point he got tired of it — despite the constant military clashes, the colonel considered it necessary to take care of himself, especially his face, which is why he now felt most unpleasant and unkempt way just because of this god damn stubble.
Colonel Quaritch looked at his reflection in the mirror, a slight grimace on his face as he noticed the stubble. He reached up to scratch his chin, wincing slightly at the discomfort it caused him.
— Damn, this is getting out of hand.
To shave, Miles Quaritch had to use his left hand without losing balance and without damaging his right hand in the process. At first, the colonel looked ridiculous as he tried to shave his face by holding a mirror in his left hand, and a razor with his right hand. Once he was in the field, he would use a portable shaver. He could not allow stubble to interfere with his military-like image and his authority, but, in all honesty, it was also about his physical comfort.
Now, standing in front of the mirror, Miles frowned and examined his own reflection. The idea of shaving with his left hand had to be put aside for the simple reason that he would very likely either cut himself, or, even worse, do everything crookedly and shamefully, which he simply could not allow. It would seem that humanity has come up with so many useful things over millions of years, but even a high-tech electric razor now did not help the situation at all due to a broken arm... what an irony...
