In the comics, one of the important facts about David “Legion” Haller is that his father is the famous (or infamous) Charles Xavier, Professor X, founder of the X-Men. This episode finally addresses that, although with a few changes to the story.
The general insanity that is Legion continues with Chapter 21. Even the recap doesn’t sound sure what’s been going on, since it starts with “Ostensibly on Legion.”
After a longer than normal break, Fox’s Legion returns for its third and final season. The show remains just as surreal as it has been the last two seasons, although with a major status quo change.
My usual warnings, this is a season finale, so there will be spoilers. Read at your own risk, you are warned, etc, etc.
Legion careens along toward the season finale with “Chapter 18.”
Legion’s “Chapter 17″ largely deals with Melanie Bird.
Legion continues wandering through its second season as things keep getting weird in “Chapter 16.”
