We've never gotten an explanation for why Walt ran out on Gretchen during the trip to her parents' house, or why he left Gray Matter.
So I'm wondering if maybe he discovered something Gray Matter was involved in, wanted no part of it, and didn't want to disclose it to Gretchen for some reason.
In other words, I'm wondering if the next steps up the food chain in the meth manufacturing/distribution empire end up revealing a complicit Elliot Schwartz.
It seems clear that Mike fears somebody over and above Gus, thus his insistence that Walt has screwed up big time, instead of just writing Gus off and accepting Walt as the new capo di tutti capi.
