Is it Jacob? by TST

So I was watching Namaste last night on ABC.com and noticed something that could be very important.

In the scene where Lapidus is giving his speech to the 316 survivors, there is a man in khaki pants, a blue shirt, and a leather jacket on that looks A LOT like Jacob. At 13 minutes and 50 seconds into the episode (on ABC site) it shows the man walk from the middle of the group to the outside. As Lapidus and Cesar are talking, it only shows him 2 more times, once at 14:46 and once at 14:51, but it doesn't show his whole body, just his back and the top of his head.

If it is Jacob, maybe everyone else cannot see him and he is always there. This has potential to be a big clue. Check it out and tell me what you think...
