Season: 1–6, Episodes: 43, Faction: Survivors
Vincent is Walt’s yellow Labrador retriever, and the only canine survivor of Oceanic Flight 815.
3×10 – Tricia Tanaka Is Dead
Vincent emerged from the jungle to Hurley and Charlie with a human arm bone in his mouth. The hand on the arm held a key chain with a single key and a rabbit’s foot. He led Hurley back into the woods, and eventually to the DHARMA van from which the arm and key originated. Vincent remained with Hurley, Charlie, Jin, and Sawyer as they fixed the van, and later went on a joyride with them when Hurley was able to restart the engine. (“Tricia Tanaka Is Dead”)
3×14 – Exposé
Vincent pulled the blanket off Paulo and Nikki’s paralyzed bodies when they were presumed dead by the other survivors and awaiting burial. It is highly likely that Vincent knew they were still alive, given a dog’s heightened perceptions. This wasn’t picked up by the survivors, who buried the couple alive later that same day. (“Exposé”)
3×20 – The Man Behind the Curtain
When Locke and Ben travelled to the cabin to speak with Jacob, Locke discovered a painting of a dog inside. (“The Man Behind the Curtain”)
3×21 – Greatest Hits
Vincent was briefly seen on his leash with Hurley and Claire when they were leaving the beach for the radio tower in a bid to call for rescue. (“Greatest Hits”)
3×22 – Through the Looking Glass
Vincent was also seen leaving the camp and present at the radio tower, still under the care of Claire and Hurley. (“Through the Looking Glass, Part 1”)
4×01 – The Beginning of the End
Still under the care of Claire, Vincent was present when the survivors split into their two separate factions, and was taken by one of the survivors to join Locke’s group, due to Hurley and Claire’s affiliation with Locke. Hurley, Locke, and the other survivors who wanted to evade the Kahana crew walked off into the jungle with Vincent, headed for the Barracks. (“The Beginning of the End”)
4×02 – Confirmed Dead
The following day, during their trek to the Barracks, the group came across Charlotte Lewis after she had parachuted to the Island. After being quizzed by the group, Charlotte became alarmed that this group didn’t want salvation, and she eventually became their captive. Noticing she had a homing beacon to alert her location to her fellow crew members Miles Straume, Daniel Faraday and Frank Lapidus, the beacon was attached to Vincent and he was set free into the jungle to ensure that they wouldn’t be found. While trying to track the missing crew member, Jack, Kate, Miles and Daniel were shocked to find Vincent in her place. (“Confirmed Dead”)
4×06 – The Other Woman
Vincent was then taken in by Jack’s group and took refuge at the beach camp. After Charlotte and Daniel fled the beach camp to deactivate the Tempest station, Sun and Jin took Vincent as they searched for them. (“The Other Woman”)
4×09 – The Shape of Things to Come
A few days later, when a body washed up on the beach from the freighter, Vincent relentlessly barked at it while Bernard called for Jack. The body was later revealed to be that of Ray, the freighter’s doctor. (“The Shape of Things to Come”)
Vincent is briefly visible in the background after Daniel first returned to the beach on the Zodiac raft, and can be seen on the left behind Juliet. Vincent was on the beach when Ben moved the Island. (“There’s No Place Like Home, Part 2”)
5×02 – The Lie
Vincent was on the beach when Bernard attempted to make a fire, after a flash of light brought the survivors to 1954. When the flaming arrows started to fly out of the darkness, Vincent was seen running away. (“The Lie”)
5×04 – The Little Prince
Vincent’s collar was later found at a ravaged beach camp in the future by Locke after one of the time flashes. (“The Little Prince”)
5×16 – The Incident, Part 1
Three years later, after Sawyer, Kate and Juliet escaped from the DHARMA submarine and floated ashore, they discovered Vincent on the beach along with Rose and Bernard. The three were very pleased to see him in such good condition. Vincent had been living with Rose and Bernard the past three years in their cabin.
When Ilana, Bram and the other survivors visited Jacob’s Cabin, Ilana saw the painting of a dog but this time it was sitting on its side. Once they left the cabin and headed off toward the statue, Ilana decided to burn down the cabin. (“The Incident, Part 1”)
After the incident, Jack’s group time-traveled back to the present. Vincent did the same, along with his owners Rose and Bernard.
6×17 – The End
After flashing to 2007, Vincent continued to live peacefully with Rose and Bernard. At one point it is believed that he went to the well where Desmond was trapped, as evidenced by the Man in Black pointing out dog scratches in the ground. He presumably accompanied Rose and Bernard’s rescue of Desmond and return to their camp. When the Man in Black approached and took Desmond, Vincent remained behind with his owners.
Sometime after Jack had saved the island and stumbled away from the source, Vincent found Jack in the very same bamboo grove where they first encountered each other. Vincent laid down beside Jack and comforted him as he died, suggesting the cyclical nature of the island, the overriding theme of nature, or the theme of Live together, Die alone, that is contradicted here with Vincent staying with Jack as he passed. (“The End”)
