Many Sides of Jane

This absorbing docuseries calls it a wrap, at least for now, with two new back-to-back episodes, starting with “Ashley,” which introduces a new and self-destructive part of Jane’s splintered psyche. Dr. Waters immediately begins trying to crack Ashley’s tough exterior to get to the underlying pain. Then, in the season finale “Jane’s Beautiful Brain,” Beth — a 10-yearold part of Jane — lends her assistance when Jane journeys to Boston to participate in an experiment.
