Final task: plan for the questions in my second interview

I recently posted a blog where I introduced my second subject to the documentary. Of course, with my first interview, I had already done a preliminary task with the same subject, so I already had an idea about what types of questions I should ask, however, I haven't ever done an interview with this subject before; so I will need to plan the questions that I will be asking in my interview. I want to keep the same structure of the interview as the first one, by cutting down the number of questions, therefore allowing much more focus on individual topics. 

The subject has a background in charity work, which I believe is a key aspect of this interview. I have already stated in my introduction I don't plan to ask very personal questions about this subject, but more in fact questions about which answers are solutions to this crisis. Meaning I will be asking questions such as...

If you were me, how would you help my friend Alexei?

If you were Alexei, what would you do to try and escape the trap of loneliness?

How should people deal with loneliness?

As before I want to keep on the topic of loneliness, meaning that the interviews will both be fluid and transparent within the documentary. I will later post a blog that has the finished and confirmed questions that I will be asking in my final interview.
