Lennon was an apparent member of the Others stationed at the Temple at the time of Hurley, Jack, Kate, and Jin's arrival. The four survivors had come to the temple, at Jacob's behest to Hurley, to attempt to revive and heal Sayid, who was dying from a gunshot wound. Lennon appeared out of the temple along with Dogen, and acted as a translator for the Japanese man to the survivors. Dogen instructed Lennon to have the survivors shot, which was only stayed when Hurley announced they were sent by Jacob, and produced proof of this claim.
Following this, Sayid was brought into the Temple and placed in a wading pool, where he was held underwater by Others. Dogen then turned over an hourglass, and forced Sayid to remain underwater until it completed. Sayid, however, went prone prior to this, and it was Lennon that translated the announcement of Sayid's death to the survivors. Lennon and Dogen then spoke with Hurley privately in a garden room, where it was revealed that Dogen spoke and understood English perfectly, and did not necessarily require Lennon's services. However, Dogen found the English language distasteful, and preferred to be translated by Lennon. It was here that Hurley announced Jacob's death, which greatly shocked Lennon and Dogen, who expected Jacob to arrive at the Temple.
Stunned by the news of Jacob's death, Dogen and Lennon sounded an alarm which called all Others present to fortify and strengthen the Temple's exterior defenses, as well as line the outer rim with a dark powder. Hurley inquired if these measures were to keep the survivors locked in, but Lennon stated that it was to keep an outside force from entering. Lennon then approached Jack and demanded a private conversation with him, to which Jack refused. Lennon then stated that he could come willingly, or be forcibly escorted, but the fact remained that they would have the conversation in private. This altercation was interrupted when Sayid, seemingly dead, regained consciousness. (LA X)
Lennon was present when Claire appeared to deliver a warning on behalf of the Man in Black and ordered her capture. She was placed inside a pit and when Kate demanded to see her, Lennon granted her two minutes. After Sayid murdered Dogen, Lennon screamed at him that Dogen was what kept the Man in Black from entering the Temple. Replying that he knew, Sayid slit Lennon's throat, killing him and leaving his body floating in the Spring.(Sundown)
