Spock/Relationships/Romances/Leila Kalomi

On stardate 3417, Spock was infected by Omicron spores while on Omicron Ceti III by Leila Kalomi, who was serving as the Omicron colony's botanist. The spores broke down Spock's emotional control, and he confessed his love for Kalomi. Their time together was short-lived, however, as Kirk deduced a method of destroying the spores with intense emotion and induced anger in Spock.
Once free from the spores, Spock freed Kalomi and the rest of the planet from their influence. He later reflected that his time with Kalomi was the first time in his life at which he had felt happy. ()
