MIDSEASON FINALE: In the most recent episode of this always surprising and evolving series, Michael’s inhuman assistant Janet saved the day – then saved everyone by whisking them into her realm. It’s a mystical place we’ve never seen, but is the place where Janet, and all her lookalike, Siri-like counterparts, were created. And tonight’s new episode, the last before a two-month hiatus, is called “Janet(s),” so I’m guessing we’re going to encounter more than one.
