The only thing raising Kev’s spirits from the pit of despair is that he’s with his daughter. Not because he cares for her, but because he likes having his enemies around so he can shout at them. Kev has a wish to be mean to Alice. He wakes her up.
Alice hasn’t seen her father for days. She has no idea what has led Kev to be so angry.
She just knows that he’s here, and he’s yelling at her.
She begins to respond and accuse him of being mean again, in a mirror of their earlier arguments. But where Kev had only threatened with physical violence before, this time he acts.
