There was a whole lot more about Hazlet that made him get scared,at the thought that something was wrong with her.
Not that he didn't know that there was a lot going on with her, she's physically and emotionally stressed out
But he didn't see that as something that would have her sweating every night they were sleeping and also her body temperature changes too at a fast rate.
She doesn't know that he knows about the changes in her body,which he wondered if that was as a result of the change in the environment.
There's a fifty percent possibility that it has to do with her environment,did he forget to mention that this was the first time she's travelled outside the company?
Although this wasn't the way he intended on making her stay here in Paris with him,he has a whole lot of surprises planned after their wedding and their wedding night.
