I'm honestly underwhelmed.
The introduction of teenaged William as an illusion-casting self-healing Mutant was slightly unexpected in the middle of what started out as a Monster of the Week (Ghouli), and it seemed part of a disjointed plot to bring some cohesion to a muddled MythArc that had spiraled out of control.
There was a lot of plot ideas thrown at the screen in a 60-minute episode - which begged whether this should have been one of the epic two-parters that informed the MythArc episodes from Season Two forward - and because of that I felt the character development for William went nowhere. He was not given enough time on-screen to show depth.
Although if Smoking Man is his biological father, he's taking after his old man by double-dating and two-timing multiple girls at one time.
Damn that biological urge to breed.
