"Shall we begin?"  Those words kick off the latest promo for FX's new series "Legion," and given the near-universal acclaim the premiere episode garnered it's safe to say that thing have well and truly begun, indeed.

Based on the titular mutant created by artist Bill Sienkiewicz and legendary "X-Men" scribe Chris Claremont, the series centers on David Haller (Dan Stevens).  Diagnosed with schizophrenia as a child, an institutionalized David comes to the realization that the voices he hears and the visions he experiences may be real and potentially the result of mutant abilities.  Able to manifest an as-yet unknown number of abilities and personalities, David may well be the most powerful mutant on Earth, and with a coming war on the horizon, David's powers will prove key the conflict.

While previous promos leading up to the series premiere highlighted the show's trippy aesthetic, stunning visuals, and David's potentially unreliable narration, this latest tease puts the series on more solid narrative footing.  With the focus firmly on David, the mysteries surrounding Dr. Bird (Jean Smart), and the overarching conflict, "Legion" is beginning to slowly shed light on where the series plans to go.

The first episode of "Legion" thrived on ambiguity and a sense of narrative uncertainty, in no small part thanks to the performance from Stevens.  The audience can only be kept in the dark for so long, though, and it will be interesting to see how "Legion" pulls together its seemingly divergent threads.

Starring Dan Stevens, Aubrey Plaza, Katie Aselton, Jeremie Harris, Bill Irwin, Rachel Keller and Amber Midthunder, “Legion” airs Wednesday evenings at 10PM on FX.
