Tough call, but if the chimeras weren't too badly injured and are able to get out of the rubble, they may help Ed (since Kimblee betrayed them).
So, now I wonder, just when did that jerk get a second stone?? >_< Someone needs to just chop off both his hands. I feel sorry for Ed, with his ideals being torn apart by everyone around him at this point.
*is also looking forward to learning more about Hohenheim right now*
