The Ending Of Kingdom Season 2 Explained

Season 2 of Kingdom revealed many secrets about the series' zombie plague. Unlike other undead outbreaks, this one is caused by worms that live in a special plant, and the worms are extremely hydrophobic. Submerging a body infested by a zombie or bitten by one drives the worms out, which kills the zombie and prevents zombification, respectively. But where did the plant come from? That question is answered, albeit only partially, in the final episode.

In Season 2's finale, Crown Prince Lee Chang learns that the plant originated from China, and that it traveled to Korea by way of a traveler. The man who brought the plant tried to sell it as a death panacea, but nobody bought it because, well, who would believe such a snake oil claim? But, that only answers the where and when; Lee Chang still has to discover the who, what, and why.

Kingdom's final episode provides several implications, but no true answers. Did the person who sold the plant to the traveler just pass it off in a desperate bid to sell it, or did they know it caused zombies? And if so, did they sell the flower in a deliberate attempt to weaken the country from within, possibly as a prelude to an invasion? But, the season's biggest mystery is the woman with the boxed zombies. Who is she, and why is she playing the role of undead postmaster general?

We probably won't learn the answers until Kingdom Season 3, assuming the show receives one.
