Re: [THE CURRENT OPTIONS]
Option one is Jace who's--er, a wizard, to put a voluntary trigger in our heads to block out the information if we think it's necessary.
Option two is to have another Judge seal the information away, with uncomfortable side effects if we try to talk about it.
Option three is basically smashing Mirror with a metaphorical hammer while we remain kidnapped.
. . .
No sarcastic remarks from me if that's still confusing.
