According to the paragraphs 8-12 from The Upturned Face, it can be said that personality differences between Lean and the adjutant are the following:
On the one hand, Lean is <u>practical and brave</u>, since he was the one who plucked up the courage to touch, with his bare hands, the body of the dead officer to gather the items they needed.
On the other hand, the adjutant is <u>speculative and wary</u>, as he is the one giving the instructions to Lean for doing "all the grisly business".
