"Master Bruce, just in time for lunch." "Thanks Alfred," once everyone was there they started introductions. "Hello Mr. Wayne. I'm Kalder, this is Conner, and Megan." They waved as they heard their name "Pleas, call me Bruce. Hello to you all. I'm sure you know Wally and you've met my sons. By the way we know that your the young justice league. Well, I must be going. Have a good day. Wally, Dick, you know the rules. Do a tour then go over them." He said while running out the door. "Oh, Damian and  Barbra are coming tomorrow or was it tonight? so set up the rooms."

Later

"And this is the library, and that completes our tour." Said Dick. "Wally, can you go get Jason and Tim so we can review the rules?" Wally nodded and returned with a sleeping Tim in his arms and an angry Jason on his back. The girls awed when Tim woke up. "Now that everyone's here we can start.
The rules are:
-No cooking without Alfred's help
-Don't let Damien in the weapons room
-Don't go into Bruce's office
-Don't enter a bedroom that's not yours without permission
-Jason no smoking inside
-Don't make Jason or Damien mad
Umm, I think that's it. Any questions?" Before anyone could say anything the doorbell rang.

Who could it be???
