check this out aswell. i watched the episode on my housemate's laptop, and he watched it again and just showed me something..... u see jacob for a split second, but if you pause it just right you can have a good look at him. just after jacob goes scitso because locke shines the torch on him, ben grabbs the chair and tells jacob to stop 'you've had your fun', then jacob sonic booms ben into the wall and THEN for a split second you see him. pause it
