I know. Didn’t they specifically say that the pen couldn’t write dead people back alive and now that is what Cruella is suggesting? Stupid show.
It is confusing. Basically, Cruella said the apprentice lied to Henry.
In 4×22, the apprentice said,
“Not even an author can bring back the dead, no matter how much he might wish it…Your father, Baelfire, died in the real world, and that sadly can never be undone.”
Cruella and Henry then had this convo in 5×13,
Henry: You’re already dead. No one can change that.
Cruella: Actually, one person can: the author. Oh yes, that’s you now.
Henry: No, the apprentice told me it’s impossible.
Creulla: Because he didn’t want you to! But Henry, you can. The author’s power if far greater than that bearded old man wanted you to believe.
So either Cruella is lying about the apprentice lying to Henry, or she is telling the truth. As mad as she is, I’m inclined to believe her. What does she gain by lying about it? Nothing. What does she gain by being honest? Potentially everything.
