This issue moved along so fast, I still can't believe so much stuff happened.
As you may have heard by now, Thor shows up the end with a wicked lightning strike aimed at Hercules. And he's pro-registration too. Marvel is going to have to explain to me how he got here from when we last saw DB pick up the hammer in FF #438.
And, over at Newsarama, they just debuted both the full McNiven and Turner covers to Civil War #4. Crazy stuff.
I just bought the issue during my lunch break and have to get back to work now. When I get around to it, I'll write a full synopsis.
