I’ve just finished my second reread of Carry On and I still have some questions.

At the end, the Mage is casting a spell on Ebb. “Easy come, easy go. Little high, little low. Carry on, carry on.”

I know that’s Bohemian Rhapsody but I’m confused as to what the spell was supposed to do. I thought the Mage was trying to take Ebb’s power, but how would Bohemian Rhapsody help with that?

And my second question is about the title of the book. I did notice characters (and the Mage at the end) saying “Carry on,” but I never real understood why this was significant enough to be the title. What was the author trying to say by picking that title?
