Also, be sure to check out the next episode of DEXTER's Wrap Up podcast, featuring David Zayas (available Sunday night after the episode).
Hannah is 'off' somehow. Her affect is...wooden. Now she speaks of 'rumour' that Dexter was the last person to speak to Wayne before his suidice by Mack truck. Why does she care, given especially what Wayne had told Dexter-- that Hannah wanted nothing to do with him? Strange. Why does she wish to know his last words and re-live something she said she was 'trying to put behind' her?
