Lost...i am lost....

two episodes have happened , whats up with who?
ok....The hatch was opened. Locke, and Kate opened it, and Kate went down then this light came on, and she was gone. Locke went down after her and was gone. Jack came looking for them and went down the hatch. He then found this guy with a gun against lockes head. This guy had been in Jacks past. He was the one that told Jack that miracles can happen when Jack was defeated about his soon to be wifes medical state.So he was in the hatch, living in this underground home or something waiting for the world to end or something.... meanwhile kate is in a vent, after she was tied up and put in a food cellar.
next.. the people on the raft....or the raft, that got blown up...well sawyer got shot. but he is ok, he ends up taking the bullet out with his hands. Micheal...is totally sad..and broken up because Walt got taken by people. He is determined to get him back, after losing him before to his gf/exwife. Him and Sawyer are constantly bickering...until Sawyer goes to get another part of the raft and a shark goes after him..then micheal shoots the shark. They eventually get back to the island. While they are thankful to be on the island, they finally find Jin. He comes running up, and says "others" and behind him are like jungle people...
Everyone else is at the caves doing their own thing. Charlie, still has that statue of Mary, with the cocaine in it...he better not snort any of it!!! ooo..and Shannon goes to look for the dog, and sees like a ghost of Walt. He has like water coming out of his mouth....and he says or tries to talk....he says something like, "press the button..no buttons bad"or "don't press the button, button is bad.."one of the two lol i dunno. so where is walt? is he dead? is he like some sort of prince somwhere....where????what???theres to many questions that need to be answered, but hopefully soon.. some of them will be.
