Valerie is not dead only forgotten by all but a few.
Her Soul is trapped in Hell and her body is trapped in a secure psychiatric wing that resembles the Hell that keeps her Soul.
Only a few have any real belief in her innocence and not all of those are friends or allies.
Meanwhile Tim goes from strength to strength.
He has 999 rooms to fill before his quest is complete.
His ineptitude is almost as frightening as his ruthless use of the powers he has stolen.
Even if Valerie does manage to recapture her Soul, that alone will not secure her bodies release from it`s cruel prison and even if it did her Soul may by then be even more corrupted than Tim`s.
TIM DRAKE Pt Two Soulsister
