this weeks cliffs notes:

-Walt Sr and sawyer get onto some driftwood, avoid sharks, find a pontoon.
-Morning comes, they see the island and are able to make it back to shore
-once on shore, Jin comes running out with his arms tied behind his back yelling in Korean, saying something about the "others".
-As they free him, they all look into the jungle and see 4-5 people with huge sticks in their hands coming towards them

-Locke locks Kate into a room at the request of the dude in the hatch, kate gets free and finds she's in the kitchen with TONS of stored foods. She crawls through the shafts and watches the showdown between Jack and the mysterious dude.
