Or Etrigan's entire presence, or Phantom Stranger suddenly showing up at all lol.
I mean, Child showed up, did some shit around then left with Klarion still around, so she's not doing the illusion of change, what likely will be an "illusion of change" will be Fate's situation, since Zatanna is so sidelined as is, Fate is even worse, so Giovanni not being Fate's slave anymore may not mean much for the plot, or characters, but we'll see, I don't expect it to matter though lol.Getting some "illusion of change" vibes.
Thinking of it, this cartoon runs on illusion of change more or less since season 2, despite all the nasty bullshit the heroes may do, the relationships stay the same, and Light only really loses irrelevant members nobody cares about, like Orm... Guess the Geo Force situation is a step at avoiding continuing that to such an extent, but we'll see about that eventually, unless YJ gets cancelled, again.
