Something has been nagging at the back of Twilight's mind for years now. She looks out of the window, and with every passing year the number of changelings she sees increases, that of other creatures decreases. She decides to have a talk with Thorax about it, to sort out her thoughts.
The Changeling King is more than happy to help her figure out what's actually happening. And to make sure she's on the same page as him on the matter.
