I predicted this pretty much early on. There was just no way Fraction was going to have Emma turn on Scott, her loyalty to him's been a staple of her character for some time (and I don't even particularly like the coupling). She's said that she tells him everything because his mind can't hide anything from her. And Scott was too nonchalant about her defection for him not to know what she's doing.
As for Namor, he was never going to be taking orders from someone like Norman. And I wonder if he heard the threats Osborn made to the Richards kids? Namor wouldn't like that either.
