Agent []

The grey-suited man
This agent, from an unknown point of origin in the timeline, recruited La'an Noonien-Singh to complete his mission in Toronto, Ontario on Earth, after he was shot and later died from a bullet hole in his abdomen. After he arrived aboard the USS Enterprise, he gave Singh a temporal device that he was carrying, before telling her she had to get to the bridge, which she interpreted as the Enterprise bridge. Immediately after he died, his body disappeared from the corridor where he laid.
His mission was later determined by Singh to stop the Romulan agent Sera from completing her assassination of a young Khan Noonien Singh, La'an's ancestor. (SNW: "Tomorrow and Tomorrow and Tomorrow")
