In this flashback, Nina and Matthias—who are mortal enemies—are thrown together and forced to rely on each other to survive. And significantly, Nina demonstrates immense humanity and compassion here when she saves him because he’s a fellow person. Even though he’d like to see her dead, she still insists that saving him is the right thing to do. In many regards, this makes her more human than Matthias (who believes at this point that Grisha aren’t human). Matthias has essentially given up his humanity as he learned to embrace the drüskelle cause.
