   "I couldn't believe it," Clark said.  "I think she was actually going to kill him."
   "Did you expect any different from someone who claims to be an Amazon?" Bruce replied.
   Clark, Bruce, and Bart sat in the penthouse living room.  It was only a few hours after Diana's fight with Deadshot, and Clark had felt the need to let Bart and Bruce know what had happened.  Lois and Bruce were still on rocky terms, so she stayed home.
   "I don't get it..." Bart said.  "Diana's always been so... nice.  I mean, she's sorta been like my big sister.  I don't get why she'd go all crazy and almost kill a guy."
   "She was hurt," Clark said.  "Pretty badly, I think.  She was bleeding, and she looked like she'd been beaten up a bit.  I don't think she was thinking straight."
   "We need more information," Bruce said, his brow furrowed in thought.  "You said you only got there after the fight was over.  Maybe there's something we're missing."
   "I hope so," Clark said with a sigh.
   After a few seconds of silence, Bart spoke up.
   "Well... what if she did kill him? ...Isn't it better if he's dead?"
   "Maybe," Bruce replied, "but that's not her decision.  It's not any of ours.  It's up to the law to decide his fate."
   "It's not just that," Clark interjected.  "No one's beyond helping.  As long as they're alive, there's a chance they can turn around and become a better person.  If they're killed, that chance gets taken away."
   Bart nodded in understanding.
   "You know," Bruce said, "you three have never really set any ground rules as far as your... 'crimefighting' goes."
    Clark thought about that for a moment.
   "I never thought about it.  We've never needed to before.  We just knocked the bad guys out and left before anyone got a good look at us."
   "That's something I wanted to mention, actually," Bruce said.  "Are you sure no one saw you or Diana today?"
   "Pretty sure," Clark replied. "Why?"
   "You probably need to start thinking about ways to hide your identities.  Unless you and Diana can constantly move at super-speed like Bart, there's no way to keep yourselves from being recognized forever."
   Bruce had a point.  Clark wasn't really sure what to do about that.  But that also wasn't the immediate issue.
   "We should probably figure out these other 'ground rules' first."
   "Pssh. 'Ground rules,'" Bart said sarcastically.
   Bruce and Clark looked at him quizzically.
   "You and Diana don't even need to walk on the ground," Bart explained, turning to Clark.  "I don't even think 'ground rules' apply to you guys."
   "The same rules apply to everyone," Bruce said firmly.
   "No, he's right," Clark said quietly.  "Diana was raised as a princess on a 'paradise island'; I don't know if she thinks of herself like everyone else."
   "If I may be so bold," an elder voice said from the side of the room, "perhaps someone should actually speak to Miss Prince herself about these matters."
   The three boys turned to see Alfred standing several feet away.  He was so quiet and unassuming that they often forgot he was there, but when he chose to make his presence known, his advice was always welcome.
   "Yeah," Clark said, "I hadn't really thought much about it, but someone should really go and see if she's okay."
   "Cool," Bart said casually. "I nominate you. Bye!"
   Before any of them could blink, Bart sped into the elevator—sending a gust of wind through the living room—and hit the button inside, closing the doors in front of him as he smiled goofily.
   Clark and Bruce exchanged glances, then rolled their eyes.
   "He's probably right anyway," Clark said, standing up to leave as well.
   "Clark," Bruce said in a very serious tone, "...if Diana won't agree to calm down, you need to be prepared."
   Clark frowned. "Prepared for what?"
   "...For the chance that you might have to fight her.  We can't have her going around the city, killing off people she deems fit to die.  You might be the only person who can actually stop her."
   Clark took a moment to stop and seriously consider that.
   "...Let's not assume the worst.  She hasn't actually done anything yet.  Let's just talk to her."
   "Fine," Bruce said with a shrug, "but be careful."
   Clark nodded and left.
