Pretty good reddit theory about where the rest of the season might be going:
"It wasn't me, it was Ignacio!" - A theory about the rest of this season (Spoilers) : betterCallSaul
It isn't technically a spoiler b/c it's one guy's theory, but if you don't like to have the surprise ruined by anticipation, then don't click b/c he takes it through the end of the season.
