What even??? It definitely has to be a mental thing they can't die, they can't feel pain. It's probably mental pain or something.. I wondered why they'd hire you though maybe they want pain? But why try and attack you is the question? To scare you into doing something to them? Maybe they're tired of it. They way he said they could not feel pain for a long time sounds like he was over it. I could be wrong. Maybe they want you to be the same as them idk.. It's all so weird how they set this all up. I know one thing I'd love to have their eyes. Just saying.
