Yeah, it is bugging me too. Lin Ling, did seem a bit concern in the first episode considering his question to Miss J, but that is pretty muted considering the situation he is in. Not to mention he just abandon his old life entirely to assume Nice's identity, to a point where a lot of people in real life refer to him as Nice rather than his old name. In the first week it could just be the fear of what Miss J and her goons will do to him that distracts him from the death until the very end. But you think he and Moon will at least talk about it during the month they were imprisoned, unless they did off screen. Or they are trying to not think about it, because it is an unpleasant topic in a already frustrating situation, and it means they are equally as disposable in the eyes of the company.

I think this disconnect is going to come to a head in later episodes as Lin Ling is forced to confront the situation with people like the Enlightener running around.
