Cartoon Network has been messing with the credits at the end of all their shows. On Young Justice, they mash up the credits for multiple episodes, so on any particular episode the credits they provide are completely useless. Greg Weisman posts the actual credits from all episodes on his site Ask Greg. Here's the relevant one for ep 2: http://www.s8.org/gargoyles/askgreg/search.php?rid=880

Also, I think you are spot on regarding Artemis and Superboy. Actually, I think the Superboy/Miss Martian scene in the latest episode was designed to set up the fact that Superboy's mind control has already been activated (which is why he, and later Megan, was acting so weird).
