It figures, she thinks, that the first and the most current person to ask about the soul business, here, is the Doctor. Different faces, mostly the same man. More flailing, perhaps. And the bow tie. Fortescue heavily considers how to word her answer.

"The only way to put it back is to kill Jazz. And that's not an option. For obvious reasons, and for one other. It's a prevention system, yes, but it doesn't prevent all damage."

Her soul is still, after all these years of heavily using Blood magic, warped and damaged, but less than the alternative. How damaged? There's no way to tell. And Fortescue is absolutely certain she doesn't want to find out. What scraps of information she was able to dig up, more recently, indicate that the side effects of soul damage are... well, alarming.

And she doesn't know, really doesn't know, what she'd do without Jazz.

"I really don't want my soul back. The tether works just fine."
