The only thing i found shocking ws that batman revealed his identity but withing the context of what is happening he got through to Hal and he just turned the loose cannon into a field general. I was kind of shocked that hal did not know who bruce wayne was too.
Batman is clearly the strategist of the team and will get supes back.
Grayson was pretty good as Batman, but ultimately he is Nightwing. I wish they gave Nightwing a more prominent role in the DC universe and I also hope at some point in some run Batman and Nightwing work together full time as a Batman and Robin type duo.
