In the sixth installment, we get a glimpse of a conversation between Juliet and Ben, regarding Walt, who is obviously being held in Room 23. The dialogue here is fascinating, because you can definitely get a sense that the majority of the Others are frightened by Walt’s unique abilities, as Ben gives reference to Jacob as well:
JULIET: This is your responsibility. You were the one who wanted him here.
BEN: Jacob wanted him here. He’s important. He’s special.
JULIET: He’s dangerous.
BEN: He’s just a kid Juliet. He’s a child.
JULIET: He’s just a child? Come see.
We then get to see a pile of dead birds, which Walt presumably caused via his abilities. The sets up for Season 4 nicely, as we got a glimpse of Walt during the finale, but obviously will see much more of him during the story arch this season. I think it will be interesting to see where he aligns himself within the framework of the show (the obvious answer is with Locke, but we’ll see). If you have yet to see this mobisode, you can find it here.
