Hurley helps Richard make his peace with Isabella, says they must stop the man in black

Back in the present, Richard makes his way back to the ruins where he digs up Isabella's gold cross. He looks up and starts yelling that he was wrong and that he changed his mind. He's opening that the man in black (Locke in this time) will hear him.

He turns around to find Hurley instead who tells him that Isabella sent him and she wants to know why he buried her cross. Hurley says that she is standing right next to Richard and that he'll tell Richard what she says. She wants him to close his eyes, just like she told him to do when she was dying.

She tells Richard that it is not his fault that she died and it was just her time. She says that he has suffered enough and when he says that he misses her, she says that they are already together. Isabella then disappears.

Hurley then tells Richard that she said one more thing. She said that they have to stop the man in black from leaving the island or "We all go to hell." We then see an extra-wide shot where we can see Locke looking over the valley where the are.

Again the question is, what havoc will be unleashed if Locke (the man in black) successfully leaves the island?

Isabella appears to Richard on the Black Rock, smoke monster 'grabs' her + the boar

Chained inside the Black Rock, Richard struggles to loosen a floorboard. It starts raining and he struggles to reach some water to drink, but can't reach it. Later he manages to remove the nail from the floorboard and begins to chip away at the wall where the chains are attached.

Later, Richard wakes up to the sound of a boar nibbling away at one of the bodies. As the board charges at him, he drops the nail just out of reach.

Richard passes out again, and is later awoken by the sound of Isabella's voice. She comes over to him and tells him that hey are both dead and in hell. She says she is there to save him from the devil. Suddenly, they hear the sounds of the smoke monster. Richard tells her to run away and when she heads up to the deck, she lets out a blood curdling scream. Richard calls for her, weeps and falls to his knees.

So here's the big question. Was Isabella the smoke monster? It would seem so because she is dead, but can the smoke monster be her but also appear to be above the ship, essentially in two places at the same time?

Richard returns home to find that Isabella is dead

Richard returns to his home to find that Isabella has died. She had a bible across her midsection when she died. Richard weeps over her body and then a constable (a law enforcement person) barges through the door.

Richard in Tenerife, Canary Islands, 1867, Isabella is very sick

In Richard's first official flashback, we are taken to Spanish island of Tenerife in the Canary Islands in the year 1867. He is riding a horse to his modest home where is wife Isabella is.

When he enters his home, his wife Isabella is sick in bed. He dampens a cloth to cool her head and when she coughs on the cloth, he sees blood on it. He tells her that he's going to get a doctor and he'll be back before dawn.

Richard gathers all the coins they have and says that he hopes it will be enough. Isabella takes the necklace from around her neck with a cross and tells him to give it to the doctor. Richard resists, but takes it. She tells him to closes his eyes and that they will always be together. He kisses her cheek and tells her "I will save you," then leaves.

Isabella telling him to close his eyes will be revisited and will be pivotal later in the episode when Hurley is talking to Richard.
