Does anyone else think Superman's attitude towards Lex here is a little OOC? I mean, they used to be friends when they were kids and in Grant Morrison's JLA run Superman said that "there's a good man in there somewhere."
The issue also introduces a new character, Simon Valentine, who will apparently be Superboy's "greatest friend-- and his greatest enemy." Even before that line he reminded me a little bit of a young Lex Luthor. It'll be interesting to see what happens with him.
