Legion: 25 WTF Moments From Season 1

As if the first appearance of our diver friend wasn't weird enough, we meet him again later in the episode when David finds himself lost in a dimension known as the Astral Plane; a dark void full of glowing green particles. David is then greeted by the being in the diving suit, who silently instructs David to follow him.

David obliges and is led through the plane and up a chain-esque ladder to the diver's home... which is a giant, furnished cube of ice. The diver then removes his suit and reveals himself as Melanie's long-lost husband, Oliver Bird. However, it appears that the time he's spent trapped in the Astral Plane has taken a toll on his memory, as he appears to be more concerned with show tunes and beat poetry than much else.

Oliver certainly has eccentric tastes.
