Re-Watching "The Constant"

More insights after re-watching the episode...

Finding Your Own Constant
At the end of the episode, Dan was flipping through his journal when he suddenly came to a page that said "If anything goes wrong, Desmond Hume will be my constant."

So, is this the first time that Daniel Faraday is reading this entry? Or has it been there the whole time? Is he now just realizing who Desmond Hume is? Reading this journal entry also made me realize that Daniel could've just as well told Desmond about finding a constant over the phone. Instead, he sent Desmond to meet up with him in the past...as if he were using Desmond so that he could have a constant, just in case something goes wrong.

Where Do I Know Him From?
You might have found yourself asking, "Where do I know George Minkowski from?" He's probably best known for his role as Benjamin in "Short Circuit". Anyone else hoping that we get a guest appearance from Johnny 5 soon?
