Christopher: Roger's Perspective

As I am playing Roger I think it is important to understand how Roger views Christopher.

Now, personally, I believe Roger finds talking to Christopher very awkward. Primarily because he had an affair and left his wife for Christopher's mum (Judy). He knows that Christopher's dad (Ed) has brought him up therefore feels a little guilty and perhaps unable to make a proper connection. I always feel as if Roger doesn't actually feel involved or know how to handle Christopher properly, or perhaps doesn't actually care. I get this impression when he greets Christopher with "What the hell is going on !?" indicating his shock at the situation. I also believe he finds talking to Christopher difficult because he knows he has done wrong by having an affair and knows Christopher was directly affected by his actions. In addition, I believe that Roger only tries to make an effort with Christopher because he is with Judy, Christopher's mother.
