Interesting - I can totally see Sheppard as an introvert, but you know what, that's not set in stone for me. I could write him as an extrovert, I think. I also would have never picked up on that particular bit of his characterization, but it does make sense of the conflicting superficial charm/inability to have a conversation about feelings thing (which is a favorite of mine, as John characterizations go). The things people see in their characterizations, where they come from - it's all fascinating, I tell you. I was waiting for your comment, I was wondering what makes John characterization for you.

I love that theory, man. I could totally buy into that theory, actually. I write him that way sometimes, even.
