We’re almost at the end of this season of Legion, and I’m not even sure where we are, geographically or emotionally. But I do know that the events of the past few episodes, tough as they may be to describe and explain, have gotten David very, very angry. And when he gets angry, things around him tend to be in grave danger. Tonight, with an important missing body about to be located, the term “grave danger” may well have a greater meaning.
