I'm not sure I like Superboy as a juicer - let's hope they don't turn it into a Very Special Episode.

I figure Batman and/or Zatara/Fate were pretty much forced to tell the rest of the League how Captain Marvel could travel between the dimensions. Or Batman made Billy do it himself. Of course Batman knew; it was pretty obvious back in Misplaced.
