SPOILS
I'm not sure what to think either...
Superficially, it was a frustrating experience. Because Better Call Saul is an illusion. You have Chuck suffering a serious injury, and you have Mike doing reconnaissance and actually taking aim with a sniper rifle, but this is not that kind of show. Chuck won't die, and Mike won't shoot.
At times it feels like an endless tease. Why else would they show us 10 minutes of Mike preparing for that hit? They are withholding payoffs wherever possible.
It doesn't bother me that much. I just think there might be better storytelling choices than this endless string of cliffhangers.
I can't deny how rich the characters have become, though. Chuck and Jimmy have never been more interesting.
I do like Mike's disorientation when he finds that note. And I can't wait to find out who his special friend is...
SPECULATION SPOILER
It's probably Gus Fring. Apparently the first letters of this season's episode titles anagram to "Fring's Back." Thus the weird spelling of this episode, "Klick."
This would 100% make sense. I can see why Gus might be stalking Hector, too. And obviously it's an essential plot move to set up the eventual Gus/Mike/Saul partnership. What if we actually get to see Mike and Gus putting Hector in a wheelchair?
