Two weeks after the accident, (Robert Picardo) develops a contemporary equivalent to barium sulfate (BaSO) radiocontrasting using a custom radioisotope with which he can identify the disparate DNA of the two original crewmen and use the transporter to disentangle them. However, Tuvix denounces the procedure; he argues that he has rights and to restore the two lost crewmen would require his execution. After discussing the situation with Commander Chakotay (Robert Beltran), Kes, and Tuvix himself, Janeway ultimately decides to proceed with the separation, acting "in absentia" to protect the rights of the two constituent men. Tuvix makes a final emotive plea for support from the crew, but finds no supporters. After the Doctor refuses to take Tuvix's life in compliance with the medical precept of doing no harm, Janeway performs the procedure herself and succeeds in restoring both Tuvok and Neelix.
