On the suit:
Right now Clark/Superman might be trying to wear whatever costume works best for the situation. To the public at large he's mostly known as, well, I'll go with the "Red-Blue Blur" in the proto-costume of the shirt and jeans. So when he's breaking into some tenement in the slums, yeah, he'll wear the rougher costume it better fits the situation. But when he meats with The League in the sewer? Well this is the time to put on your business suit and look serious.
I read Action last night, work and other things have precluded me from reading the other books, but I really
enjoyed it and thought it was probably one of the better Action books up to this point, look forward to where this goes from here.
