Floating above her bed is the sceptre usually brandished by Loki, emitting a soft blue light and glinting light from the handle.
When she sees it, his voice will deliver the following message.
Katherine, for a while I have been contemplating my position on this island and where my own power lies. Your training with the sceptre has progressed as far as it can under my tutelage. You must take your own control of your own destiny. The sceptre is yours and it will obey your powers. Use it well, my daughter.
