The longer Maria gazed upon the little man whom she had taken a liking to at first sight, the more she was sensible how much good nature and friendliness was expressed in his features. Nothing but kindness and benevolence shone in his clear green, though somewhat too prominent eyes.

One of the Nutcracker’s most defining characteristics, at least according to Drosselmeier, is his ugly physical appearance. Maria is the only one at the Christmas Eve celebration who recognizes that he possesses human qualities as well, such a kind heart and gentle spirit. This moment introduces the idea that the Nutcracker is a far more complex character than he may seem initially and foreshadows his true identity as the humble Young Drosselmeier. 

As soon as he saw Maria, he bent down on one knee, and said: "You, oh lady—you alone it was, that filled me with knightly courage, and gave this arm strength to contend with the presumptuous foe who dared to disturb your slumber. The treacherous Mouse-King is overcome; he lies bathed in his blood. Scorn not to receive the tokens of victory from a knight who will remain devoted to your service until death."

When the Nutcracker finally defeats the Mouse King, he graciously thanks Maria for believing in him and honors her with the Mouse King’s seven crowns. This attitude highlights his noble character and emphasizes the deep connection that he has with Maria. Notably, the Nutcracker’s defeat of the Mouse King does not free him from Lady Mouserings’ curse, and he must continue relying on Maria if he hopes to turn back into a young man.
