So Juliet and Jacob?

Sorry if anyone has asked this before but someone else notice that Jacob meets everyone in their flahsback except Juliet. So what might the significance of this be? It seems like there would be some since he goes takes the time to visit Ilana.

Does it have to do with the fact that she's the one to set off the bomb or are there any other theories bouncing around that you'd care to share?

I just think it's odd i haven't noticed anyone else pondering this.
