So it finally occurred to me that when Shelly's friend commented that there was "something wrong" about James it was in anticipation of his behavior later in the series. 

Because it bothered me that James, in a much later episode, would walk up to the booth of a married woman and start telling her how much he liked her in front of her husband. The whole scene was a puzzler to me. But if I reflect back on the earlier episode and accept that there is indeed "something wrong" with James. Well, maybe it makes his behavior a little more understandable.

Then that leads me to start asking . . . is there anything else I need to read into his behavior?

So I throw the question out there to anyone interested: Is there?
