After thoroughly beating the crap out of the lizardman, Arnold finally stopped. He had the information he needed. So... He decided to put an end to the monster's misery and killed it without any hesitation, just like the ones he had killed before. Only Talos had witnessed him doing so but the pleading cries of the lizardman were heard by a lot of people standing outside the room, including Nina.
She had intended to have a talk with Arnold regarding a lot of issues, like just how afraid of him the warriors were because of his temperament. But most importantly, to tell him that she was getting concerned about him and his erratic behaviour.
But Arnold didn't come out of the room for a long time. Instead, he called Alleiah inside the interrogation room for some reason. From then on, everything went silent for a couple of hours or so. No one knew what was going inside the room. Most of them thought Arnold was torturing her too.
