They're gone. [Sabriel's tone is tired, but reassuring. She was here to study, and help Doctor McCoy. But after everything that's happened... Newt deserves every bit of reassurance she can give.

We broke them Newt, smashed their mind- minds to bits and made them flee. They won't be coming back. And no one but them was hurt in the process.

[She's still not sure who she made that promise to, but either way, she kept it.]
