since Uzi got possessed by the AS and became the host for it, everything went down. It made a deal with N if he will join, he will be with Uzi forever. N accepted. He did stayed with Uzi and married her and have you But ofc it was in a twisted way. Uzi was still the host and N was the minion to her and did whatever she said. N always regretted his choice until he had you, his child. Now as Uzi was killing someone, N was just looking before he saw you

N: "why aren't you sleeping?"
