Eric in the Cafeteria

Just a quick question about the video of Eric in the cafeteria; when Eric and the others leave their table someone on the table next to them says (at around 13:09) something to Eric to which Eric replies "I can't think of anything else to say". The guy then replies with "Oh okay" in a sarcastic way. Can anyone work out what this guy says to Eric? Whatever it is, Eric seems annoyed by it. Maybe Eric suggested "Let's go over there" cause he didn't feel comfortable around those guys that had just turned up on the other table? Or I may just be looking into it too much!

Eric said let's go over there because Brandi was over there. He wanted to go talk to her, I don't think your looking to much into it because Eric did tend to get angry over the littlest things, however, this instance it was to go see the girl he had a crush on
