You know, my biggest issue with Riley might be that, for a person who seemed to be so danged obsessive about Aramus, she seemed to be able to go about her existence just fine right after he screwed her brains out and dumped her in the floor. Where was the emotional outburst? Even if not given to tears, no throwing things? No screaming fit? There's stoic and there's something else. She came across as something else.
Aramus...what exactly did he think would happen if he dropped all the human captives off at that outpost? He knew the conditions they'd been found in, knew the company had need of at least some of them. Yet, he seemed astonished that they'd been captured.
The story arc...bothers me. I think perhaps it's the unsettling notion that people could just be disappeared.
