An Innocent Man
During Oliver's dream, Fei arrives at the hideout to see Oliver looking at a photo of Laurel. He brings a cage(made out of sticks) with a bird inside and puts it beside Oliver and says "Shengcún". When Oliver asks what that means he repeats himself not explaining what it means then walks off. During flashback, Fei is sitting by a fire at the hideout toasting a bird's leg on a stick. Oliver awakens and attempts to take a grab at the stick but Fei single-handedly throws him aside. Fei then hints at Oliver to kill the bird but Oliver refuses. Fei responds again with "Shengcún". The flashback later continues with Oliver begging Fei for food. Fei watches as Oliver proceeds to kill the bird. While he eats the bird, Fei approaches saying "Shengcún". Fei tells Oliver that "Shengcún" doesn't mean bird but that it means survive. Oliver is surprised at the fact that he speaks English. Fei tells Oliver that a bird shouldn't be the last thing he kills if he wants to survive on the island. He holds up Laurel's photo telling Oliver to forget her and tells him he will not survive if all he does is stare at her photo.
