Captain Archer welcomes his old friend and inventor of the transporter technology, Dr. Emory Erickson, and his daughter Danica on board of Enterprise. Dr. Erickson is assigned to perform tests on sub quantum transportation to long distances in a desert area of the space called The Barrens and is worshiped by Commander Tucker. However, Tucker suspects that the scientist is not telling the truth about his experiment and discloses his concerns to Captain Archer. When a crew member of Enterprise is killed by a strange life force and T'Pol is wounded in her hand, Dr. Emory finally reveals that the experiment is indeed his last attempt to bring his son Quinn back from an accident with the transporter fifteen years ago.
"Daedalus" is one of the weakest and most incoherent episodes of Enterprise, with the attitude of Captain Archer risking Enterprise and its crew to satisfy the experiment of his friend to bring his son back. The hand of T'Pol, injured by Quinn, apparently is recovered by Dr. Phlox since there is no further reference to the incident. My vote is six.
Title (Brazil): "Dédalo"
