Hm I think it's probably transfer all the bad karma from the boss to him. That's why whenever he's asleep, he's haunted by all the souls blaming him. He's been trapped and imprisoned for 10 years so he can't be running around doing all the bad stuffs
From noah perspective this is a horror story - he was kidnapped brainwashed, memory erased, branwashed to work as sex worker to provide milk and then carry a baby of of godlike alien without knowing of thr life on earth he was robbed of. Scary stuff
I LOVE THIIIIIIIIS
