Daniel still seems distracted, which makes Seth kind of wonder if something's up. He had said nothing had really happened, but perhaps it's more about, well, nothing happening. Or perhaps he's homesick. It's kind of difficult to tell without Daniel actually bringing it up, so Seth will focus on trying to get him to enjoy himself. He gives Daniel a nudge with his elbow and makes a 'here we are' gesture to bring Daniel's attention to their new surroundings.
