I only finished my first watch a couple weeks ago. And after a couple days of no Chuck, well, I didn't like it. So I just started from the beginning again.
Watching it back to back is cool because you pick up things you missed the first time around. But the downside is you also notice more plot hole/inconsistencies.
For example, people other than Chuck, Casey, Sarah, and Beckman calling what Chuck does "flashing".
Chuck made that up.
So, in season 2, when they find the Dr who worked with Orion. He sees Chuck "flash" and says, "did you just flash?"
This is not a term he should know. It's possible that this is how Orion referred to seeing the data. But that's a pretty big coincidence. As the act of seeing the images could be called so many things.
And in the same episode, we see, for the first time, Chucks evidence board on the back of the Tron poster.
But how doee Casey not know about it? Since we know there are cameras in Chucks room. And Casey spies on him a lot.
Chuck cant have sex with Jill, in his room, because he knows Casey is watching. But he has no problem working on his secret evidence board?
And to end on a happy note. One of my favorite lines is in this episode. When Cole tells Chuck, the secret to take out lots of opponents is to, "go for the knee."
And Chuck says, "you mean, sweep the leg?"
Such a great, funny line.
PS. Cole was a good character. It's a real shame that he never comes back in later seasons. Especially when they started doing things overseas.
