In the first part of a two-part season finale, House finds himself dazed, confused and covered in blood after surviving a bus accident that left dozens seriously injured. Unable to clearly recall the events leading up to the crash due to his head injuries, House becomes convinced through his flashbacks that a fellow bus passenger was exhibiting signs of a deadly illness prior to the crash. Much to the team's dismay, House pushes through the pain of his own injuries, desperate to piece together the fragments of his shattered memory in order to save someone who might not even know he or she could be dying. Cast: Hugh Laurie as Dr. Gregory House; Lisa Edelstein as Dr. Lisa Cuddy; Omar Epps as Dr. Eric Foreman; Robert Sean Leonard as Dr. James Wilson; Jennifer Morrison as Dr. Allison Cameron; Jesse Spencer as Dr. Robert Chase; Peter Jacobson as Dr. Chris Taub; Kal Penn as Dr. Lawrence Kutner; Olivia Wilde as Thirteen
