In order to know when a particular character is unaware of something another character is aware of, you've to understand the story.
Your question is incomplete as the story isn't provided. I'll give an overview related to the question. A character means the person that's represented in a literary work.
In order to note instances where one character knows something that another <em>character </em>does not, the following are required:
- Read the story carefully and make sure you understand it.
- Understand the theme of the story.
- Understand the central idea that the author wants the readers to understand.
- Look at the instances where the characters had <u>contrary opinions</u> on issues.
- Finally, look at the<em> words</em> or phrases mentioned in such cases.

Answer:
In most cases - it is not possible (or desirable), & in few cases cases, it might be possible (or desirable). 
Explanation:
Profession is an occupation based on proper formal qualification, training. Eg : Doctors, Lawyers.
They require specialised knowledge (accredited) to practice as a professional. So, involvement in multiple professions is not possible (desirable) in most cases, as it hinders focus & specialised competence (expertise) in single field. 
However, in some cases, it might be possible (desirable) if the fields are related. And it also might be need of exposure for the professional. For eg - An economist might be economic consultant & a professional teacher in an education organisation at the same time.
