It's nice; Bruce likes watching people interact like that more than he likes participating in it himself - and as creepily voyeuristic as that sounds (... is), in this case it has more to do with finding Seoraj interesting. He likes hearing him talk, sue him. (Remember this for the future, it's going to look a lot worse in a few tags.)

"I like it." A quiet remark, about the variety. Language specifically, this time. There's enough around from Earth that he speaks that he can flit through and mix and match and pull a whole host of new things from the library. He did the same thing in Xanadu, when he had the chance. He's got a lot more free time, in Baedal.
