Michael has a bad relationship to his own father, a bigoted police officer who disowned him for dating an Aboriginal woman—but when he mentions that his father was “the local cop,” Derek is happy to admit that his was too. Derek’s reaction suggests that he has a better relationship with his father than Michael does, though whether that’s because Derek’s father isn’t bigoted or because Derek
is remains to be seen. Derek’s sleeplessness and chewed nails suggest that he’s nervous about something but don’t reveal what.
