What was it that Jobe couldn't put his finger on while watching the camp Genoa feed?

According to this recap/review by Michael Stets for Nerdcore Movement:

Job has already expressed deep concern for Hood’s mental status and when his friend arrives home at the trailer, he is sitting inside waiting for him (wearing a “Paws” shirt, a hilarious spoof on Jaws). He tells him he wants to delay the heist at Camp Genoa because he feels Hood is just too distracted and it may get all of them caught. Hood tells him it’s now or never and they have to do that night. Job is worried and he has every reason to be. The expert computer hacker also voiced his concern to Sugar, who, of course, tells him he worries too much.

[...]

Suddenly, Hood’s mind starts wandering and he starts having flashbacks and visions of Siobhan. As this is happening he doesn’t see one of the mercenaries sneak up on Job and attack him while he is handling the computers to breach security on the safe. Sugar tries to alert Carrie, but she cannot leave the safe due to time constraints. Finally, Hood snaps out of it and takes out the Marine before he compromises the job and Job. Job is clearly pissed off, especially since he was worried that something like this would happen.
