Once Skye had finished shaping the door, she made it so that it could slide open, and go inside the rock wall. It made the entrance wider, and left them the option to bring large things in and out of the bunker. Plus, she knew that Zazzy would throw a fit if she couldn't pop her head in on occasion to see everyone.
Zazzy wasn't used to having so many people around her at once anymore. It reminded her for following Peggy through the palace, and she was loving the extra attention.
No one had expected such an intimidating-looking dragon to be so sweet and intelligent. At least not the Alconians, anyway. The Highlanders seemed to understand that she was a good lassie, and would never hurt an innocent person on purpose.
