We have established that the thing which destroyed the USS Intrepid and the Gamma 7A system is an incredibly huge but simple cellular being whose energies are totally destructive to all known life. Both Mr. Spock and Dr. McCoy have volunteered to go in a specially equipped shuttlecraft to penetrate the cell, find a way to destroy it, and free the ship. Dr. McCoy has the medical-biological knowledge. Mr. Spock is better suited physically and emotionally to stand the stress. Both are right, both are capable and which of my friends do I condemn to death?
