In 2365, she came aboard the USS Enterprise-D on an urgent mission to intercept the Klingon ship IKS T'Ong which was about to become active after its crew had been in cryogenic stasis. She renewed her relationship with Worf, but refused to marry him when he asked her. Due to this short renewal the couple conceived a son, Alexander. To prevent the T'Ong from attacking Federation worlds, Worf posed as the Captain of the Enterprise with K'Ehleyr as his first officer to convince the T'Ong crew that the war between the Klingon Empire and the Federation was over. After the T'Ong crew had agreed to lay down their weapons, K'Ehleyr beamed aboard the T'Ong to prepare the crew for the 24th century while waiting for the IKS P'Rang. (TNG episode: "The Emissary")
Not long after Alexander was born, K'Ehleyr became Federation Ambassador to the Klingon Empire. When she was on Qo'noS, she always stayed at the Federation embassy.

Worf learned of his son Alexander for the first time. Later, she found evidence that proved Duras was involved in the conspiracy that led to Worf's discommendation; on learning of her search, Duras attacked K'Ehleyr in her quarters and killed her. Worf transported to Duras's ship shortly later and killed him in vengeance. Afterwards, Worf claimed Alexander as his son and put him in his adoptive parents' care on Earth. (TNG episode: "Reunion")
K'Ehleyr was buried at Woodlawn cemetery in New York City on Earth. Worf visited her grave for the first time after he was appointed to take her old position as ambassador to Qo'noS. (TNG novel: Diplomatic Implausibility)
- According to a reference cut from the script of "The Emissary", K'Ehleyr met Worf on Samrin's Planet in 2359. When they were reunited six years later, K'Ehleyr was disappointed at how much Worf had changed since their initial encounter.
