In one of the Young Justice Trailers there is a quick scene with Superboy and Superman that has not yet been shown in the episodes. In the scene Superman grabs Superboy's arm but Superboy is like back the 'eff off and pulls away from him. This is the link to the video, http://www.dccomics.com/videos/young-justice-trailer. At 0:52 you'll see what I'm talking about.
I'm very excited to see that scene because I want to know what makes Superman want to talk to Superboy. Like most fans, we've been thinking negatively of Superman because of his lack of interest in Superboy, so I think that scene will be intriguing to watch! Thanks to Fabiola D. (DeviantART homepage: http://fantasy93.deviantart.com/) for telling me about video!
