FUN FACT! The legend of the Fisher King — the guardian of the Holy Grail, or enchanted spring — holds that there are two custodians at any one time. There is a king, and there is a knight. Sometimes they are father and son. For some reason, the natural order of things requires the Fisher King to have an infirmity that makes him incapable of moving. He has an injury to his leg, foot, or groin. The job of the Grail Knight is to heal the Fisher King. But alas, Grail Knights are known to get distracted by selfishness or missions of vengeance and neglect their duty to the Fisher King. When this happens, the kingdom becomes infertile. No flowers; no babies. Oh, and the abode where the king and knight live pops in and out of reality, at different times and places. One more thing? The Fisher King is called the Fisher King because he fishes. A lot. Mostly to pass the boring-ass time guarding the grail. THEORY! Jacob was the Fisher King. Smokey was his knight. Smokey became disenchanted, neglected his duties, wanted out, conspired to kill the Fisher King to earn that freedom.

That whole speech to Kate about Flocke's crazy mother came out of nowhere. And Claire let go of her hate a little too easy if you ask me. Also, I'm guessing there must not be a giant explanation/payoff for the series finale, so it can be told in the final episode.
