yes ESPECIALLY since it sure seemed like they were just on the edge of KILLING HER!
Not killing. Asa planed to interrogate her, using torture, probably just psychological, if necessary.
But, now that she's aware that MC know who she is, and that her ex employer is looking for her, she will probably not even do that. It's a too high risk. It's not just about loosing a possible contact with Van Horne that is in play, one phone call from MC and her sister is in deep shit.
Haruka was clearly surprised that he know she have a sister, what prove to them that MC have the right connections ; he found, in a really short laps of time, an information that he probably shouldn't have found at all. And not only he knew that Asa is her sister, but also what was her job, and that she's still looked for. It's not the kind of information you get from the first guy you phone too, nor that leak to the first person who ask.
They also made an error by asking if he have connection with the houses, because now MC have two options. Either he warn the government, telling them where is their missing agent, or he warn the houses, what would be worse.
In the end, pissing off MC is not something they can afford to do. They can be cold, even harsh, it would have no consequences, it's just business. If he planed to snitch about them, he would have already done it. And if he wanted to threaten them, he shown that he have a lever for that. But they aren't stupid enough to think that there isn't a limit ; it's not snitching cowardly if you do it to take revenge of a torture act or a murder.
Asa can perhaps think that killing MC is an option, but she can't be sure that she'll do it in time. And someone with her qualification will never take such risk. Therefore, Cam is safe, she'll go back at home relaxed by a good orgasm.
But yet MC shouldn't have left Cam alone, especially with Asa being so cold and nearly threatening. Normally he should have phoned Devon the instant he left the house, asking her to ensure that Cam will really left safe.
Right now, he can't be sure that they are harmless. His accident, his father's death, all this can be due to Asa, since she have the knowledge and the contacts, perhaps because the father refused to present them to Mr. Van Horne, or more. I highly doubt it's what happened, but in the context their insistence should have raised at least some suspicion and made him act.
And it's not just their insistence that should have raised his suspicion. They aren't only interested by Van Horne, Asa also questioned him about Global Frontier. It's not a secret that it was his father's property, but it have nothing to do with the subject at hand. They are supposed to talk about a partnership to handle their assets, an import/export company have no place in such discussion.
I highly doubt that they want to see him to talk about real estate. I mean, seeing him in person would not tell them more than having a phone call, or an email discussion, with him. They wouldn't have more proof that it's really him just because he is in front of them, since they have no idea what he looks like (else they would have know it was MC's father). And obviously, asking him for an ID would be highly offending.
But well, all this is assuming that the story is correctly handled and wrote. So far it seem to be the case... except this "I'll left her and just go to sleep" ending, that clearly feel like a forced deus ex machina cliffhanger.
