The last two episodes of Legion, giving us extended head trips into the complex minds of Syd and Lenny, respectively, have been so inventive and exciting and unpredictable, I could hardly watch them without leaning fully forward. And tonight, in an episode I haven’t previewed, we accompany David (Dan Stevens) as he’s taken on a tour, and takes us on one, through a series of alternate realities – including one in which he’s long-haired, bearded and homeless (pictured). Which reality is real? On this show, it’s deliciously hard to tell. As Jon Hamm has begun to intone in the narrative intro to each episode, before we see clips from earlier episodes, the phrase he utters isn’t the familiar “Previously, on Legion.” It’s the much more mind-bending “Apparently, on Legion…” Gotta love it.
