Gomez a snitch?
I've seen theories elswhere that people think Steve Gomez might be a snitch for either Gus or the cartel. I don't recall the specific evidence, but they sort of stemmed from Gus or the cartel knowing things that otherwise weren't explained.
Given that everything with this show means something, I find it hard to believe Gomez is still around (been in all 5 seasons) investigating blue meth, and that doesn't mean anything. He's always been the bucket of cold water for Hank's crazy Heisenberg theories, so that makes me think he has motives to protect Walt from being discovered.
