If You Could Read My Mind (Episode 115)

William Boone (Kevin Kilner) and Captain Lili Marquette (Lisa Howard) were assigned to security detail at the conference. FBI agent Ron Sandoval (Von Flores) accompanied the Companions to their speaking engagement, but he had secret orders from Zo'or to execute the renegade who had penetrated the Taelon's psychic bond. Katya Petrenko (Shauna MacDonald), a Russian clairvoyant featured at the conference, showed herself to have not only unusual psychic gifts, but an unusual interest in Boone as well. Sandoval, impressed by Katya's extraordinary powers, set out to prove her to be the psychic intruder.

At the conference, Katya was introduced to Da'an and Zo'or. She confronted Zo'or, telling him the Taelons must change their approach to humans, or they will destroy both races. Zo'or was flustered as academics attending the conference wanted her to expand on her statement. But Katya again turned her focus to Boone, who agreed to take her to his office for a private conversation. There Katya told Boone she had come to the conference to expose the Taelons, and that she knew about Jonathan Doors (David Hemblen) and the Resistance. Boone tried to stall, not wanting to reveal himself as a double agent.

Sandoval and Zo'or had decided that Katya was the person they were looking for and ordered Judson Corr (Michael Filipowich), a professional assassin, to kill Katya. Corr crept into Katya's hotel room and took her hairbrush, planning to use the hair collected from it to set a target for a DNA-triggered weapon. The next day, Augur (Richard Chevolleau) took Lili to meet one of his friends, a neighborhood psychic named Madam Marie (Norma Clarke), to find out if Katya was a phony or a Taelon plant. Although skeptical about Katya, Marie and the entire conference, Lili changed her mind when Marie revealed personal information about Lili's estrangement from her father.

When Marie met Katya at the conference, she was overwhelmed by the Russian's incredible psychic powers. Katya, however, either did not sense or chose to ignore the threat that Corr presented, even as the assassin lurked in disguise at the conference. Lili introduced Boone to Madam Marie who told him that he and Katya were somehow linked.

Katya proves her extrasensory perception by leading Boone straight to the Resistance hideout. Doors was furious, until he proposed that Dr. Belman (Majel Barrett Roddenberry) transfer Katya's knowledge of the Taelons into Boone's brain. Despite Dr. Belman's warning that the exchange could prove fatal, Katya insisted that her time on Earth was at an end, and her mission was to leave her knowledge of the Taelons behind.

When the conference resumes, Katya's premonition proved correct. Corr deployed his DNA device at the podium and Katya was overcome with poisonous fumes.

Boone and Lili rushed Katya to Dr. Belman's lab, where they transfered her psychic memory and understanding to Boone. In these memories, Boone learns that the Taelon scout named Ma'el, who spent centuries on Earth during ancient times (see episode #113, Secret of Strand Hill), wanted to prevent the Taelons from colonizing Earth, so he gave some humans psychic abilities.

The Resistance members were astounded to learn that the Taelons were involved in altering the course of human development. But none of this special knowledge was enough to save Katya, who died when the transfer was complete.

Later, Boone met with Da'an and revealed all that he had learned from Katya. Da'an suggested that he had his own benign feelings for Earth when he agreed to keep Ma'el's "gift" to humans a secret from the rest of the Synod.
