Melanie starts at the interruption and looks up at Aziraphale in astonishment. It's sort of thrilling to be defended this fiercely, but she's also not sure what the fuss is about. Illyria's sworn an oath not to hurt anyone, and it seems to Melanie that referring to things in terms of battle and conquest is just how the god-king speaks. She doesn't mean to use Melanie as a weapon, she just thinks she'd make a good one - like a weird sort of compliment.

She can understand why Aziraphale wouldn't like it, though. She'd been thinking of pointing out that she could be defeated so long as her body was destroyed properly, but Aziraphale wouldn't like that, either. She gives his hand a reassuring pat.

"It's okay. She wouldn't try to use me as a weapon, because she swore an oath." It's not the only promise she made, either, and Melanie gives Illyria a pointed look.
