On the Island/freighter
Days 97-100 (Season 4)
When the freighter neared the Island, Lacour, with the rest of the team, travelled to it on a helicopter piloted by Frank. The team ambushed and successfully killed Karl and Rousseau and kidnapped Alex. ("Meet Kevin Johnson")
Lacour traveled with the mercenaries to the sonar fence, which was deactivated by Alex. They then invaded the Barracks, killing Doug, a blonde woman, and Jerome. Lacour and the other mercenaries then looked on as Keamy and Ben negotiated over Alex, which ended in Alex's death. Later that night, Ben summoned the Monster to attack the mercenaries in the jungle near the Barracks. Lacour, along with the other mercenaries, fell back from the Barracks as the Monster attacked them. ("The Shape of Things to Come")
Later, the mercenaries began to head to the helicopter when they were met by Frank, who convinced them to leave as soon as possible. Keamy handed Lacour a first aid kit, and Lacour began to tend to Mayhew's wounds. The mercenaries continued on to the helicopter and headed back to the freighter. ("Something Nice Back Home")
Upon the return of the helicopter to the freighter, Lacour helped unload the injured Mayhew. He was also present when Keamy and Captain Gault had a showdown on the frieghter and witnessed the death of the captain. ("Cabin Fever")
Along with the other mercenaries, Lacour escorted Ben back to the helicopter. When the mercenaries arrived to the helicopter, Keamy ordered Lacour into the jungle to be on the lookout for Others, but Lacour was snared by the legs by an Other and tripped. Lacour fell backwards, his automatic rifle firing into the air. ("There's No Place Like Home, Part 2")
- In French, "La Cour" means "The courtyard".
- Given that he tended Mayhew's wounds, it is likely he was the team's corpsman.
- Technically, Lacour is the only member of the Mercenary team to have his death not shown. However, Tony Wade who portrayed Lacour had stated on his facebook that the Others hit him on his ear with a rock and killed him, but the scene was cut.
- The name "Lacour" refers to Matt Lacour, Head Varsity baseball coach at Harvard-Westlake High School in Los Angeles, CA.
