Logan will resurface towards the end of Day 8 when Cherry Jones’ President Taylor reluctantly enlists her disgraced predecessor to assist with an escalating diplomatic crisis.Though Logan didn't appear last season, he was the cause of Soul-Patch Tony Almeida's season-seven rampage of vengeance. We first met Logan at the end of season four, when he was a hand-wringing vice president seeking the counsel of former president David Palmer. Logan later helped engineer Palmer's assassination, as well as the murder of Almeida's wife, former CTU agent Michelle Dessler. The first four hours of Jack Bauer's eighth day of real-time adventure air Jan. 17 and 18 on Fox. Find all of Ausiello’s scoop here.
