I think there might be some unexpected collateral damage —  Walt Jr. or Marie maybe?

That's true.  Maybe Hank's rationale would be that since he already presented so much of the case to Walt before actually linking Walt to the case itself, the only play would be to see if Walt shows his hand even more?  Walt's wine confessional at the dinner table a couple of weeks back may have helped Hank in more…

I've said that so many times watching this show I've lost count.

I didn't even recognize Manny until you just said it.  Wow.

It was something new and different when it first began, but now just seems repetitive and sad that it never lived up to its potential.

I agree with the Hank prediction.  This whole season has been showing how good of an agent Hank truly is, and whenever he speaks about the case with Walt, there always seems to be an undercurrent of Hank knowing a little more than we do.

"Hank already knows who you are, by the way." - Walt, to Jesse

Breaking Bad is officially the greatest show in the history of television.  I would never use hyperbole in a million years.
