At the end of the episode Skyler says to Walt when talking about Hank (who is in the hospital recovering from his gunshot wounds at the hands of the cartel hit men), "Somehow, something tells me that Hank is here because of you and I'm not forgetting that." They don't show her face while she says it or after. So did she mean:
A: she thinks the reason Hank was attacked and thus is in the hospital has something to do with Walt, or
B: she thinks Walt had something to do with the phone call that warned Hank he was about to be attacked and thus thinks Walt is the reason Hank is alive and not dead
I think A but am not positive. Walt!s expression after she says it could fit either option.
