Young, impressionable, AND a big BB fan, which makes Dan a hero to him from the start. Ian's other problem is that intelligent as he is, and as helped by his photographic memory as he is, he seems to be a little off when it comes to emotions--the kind of Asberger-y way he will answer a question literally (e.g., a, Do I look fat in these pants? type question) rather than with the emotional reassurance that is "obviously" being called for--obvious to most, but apparently no to Ian.

OR, we Ian fans can hope, you might be right and he might be faking it... but if so he hasn't told the camera that yet, even in private, so far as we've seen. And it is hard to believe that TPTB wouldn't use tape like that if they had it.
