It’s incredibly unclear to me what someone could hope to accomplish by wandering around and poisoning random poor people. Imagine that you only have one life and this is what you choose to do with it.

Finally the Apothecary I knew. Very entertaining episode, I could not disassociate for a second.

The white woman seems to be related to the past season, maybe even the previous Apothecary. They knew about the resurrection drug somehow.
