From everything I hear, Jake is a warm, open-hearted, and tender person (not unlike Jack--perfect casting!). I'd hate to see his sudden shot to superstardom cause him to feel a need to build a shell around himself, just for peace of mind. This photo gives some evidence that this may have already begun; it's an understandable reaction, but it is sad.
The most precious things in life are often the most vulnerable.
Here's wishing Jake the very best...
