Once I open this door, there is no turning back
This episode was almost an information overload 😉 . Ben and Locke go out in the jungle to see the mysterious Jacob, even though he is not someone you go out and see, he summons you. Once in the Jacob shag, Ben seems to be talking to an empty chair. Locke thinks Ben is putting on some kinda show and wants to leave, but once he does, Jacob speaks to him and says “Help Me” ! So it seems Jacob wants to be rescued by Locke from Ben. Then the whole shag goes crazy, stuff flying around etc. but Ben and Locke get out alive.
This was basically the main scene for me. The fact that Locke could hear Jacob was very frightening to Ben. His leadership was already challenged by Locke, he didnt want Locke to see Jacob.
