LOST-4/24 The Shape of Things to Come

BEST LOST EVER!
Alex has been captured by armed mercenaries. They have her type in the code for the electro-fence thing.
Locke, Sawyer, and Hurley with Aaron are playing a nice game of RISK when the phone rings and says CODE 14J. Ben is playing the piano when Locke comes and tells him. Ben reacts by pulling a shotgun out of the piano bench. He says that people are coming to kill them and they need to fortify in the house. Sawyer leaves to get Claire. On his way, the mercenaries start shooting, killing the Red Shirt castaways living with them. Sawyer ducks behind tables and fences and sees a missile hit Claire's house blowing it up. Somehow Claire survives and Sawyer gets her back to the house. The doorbell rings and it is Miles. He has a walkey talkey the mercenaries have given him. Ben won't leave the house even though they have Alex. They shoot Alex in the back of the head. Ben summons the smoke monster to kill the mercenaries in possibly the coolest scene in the history of LOST. The Locke group retreats into the woods and split up again. Locke, Ben, and Hurley go to look for Jacob.
Back on the beach, Vincent finds a body in the water. Faraday reveals it is the freighter's doctor. They contact the boat to ask about the doctor. The boat replies in Morse code and Faraday tells them that rescue is coming for them. Surprise! Bernard knows Morse code and says Faraday lied and the boat said the doctor is fine. Jack attacks Faraday and has Faraday admit they did not come to rescue them. Jacks appendix explodes.
In the Flashforward, Ben is in Tunisia and Iraq. He notices one of Widmore's men at a funeral. One of the pallbearers is Sayid. The funeral is for Nadia, Sayid's wife. Ben tells Sayid that the man he is following killed Nadia. The man confronts Ben and Sayid kills him. Sayid will now help Ben kill Widmore's people, like in Sayid's flashforward. Ben goes to Widmore's house and wakes him up in the middle of the night. He tells him that he is going to kill Penny since he killed Alex. Widmore says he wants the island.

Questions:

1. What happened to Ben in the future that he looks confused and doesn't know the year?
2. What is happening with Widmore's nightmares?
3. Why does the freighter tell them the doctor is fine?
