The survivor count shown in the title sequence is 39,675. Plot Chief Galen Tyrol holds a memorial service for his late wife Cally. As it concludes, Tory Foster tries to convey her condolences to him. Colonel Tigh and Tory later meet the Chief in his quarters. There, he confesses that he is still confused by his Cylon identity, but Tory tries to persuade him that he is perfect and that they are superior to humans. She suggests that he "switch off" his guilt, but Tigh vehemently disagrees saying that grief is human. Tory then visits Gaius Baltar in his sect's quarters.
