Forcing herself to relax the death grip she had on Ernie, Hestia stepped back to survey them. Without ever requesting him to do so, Miles handed over his wand to Hestia in the middle of his agitated, vividly-worded exclamations. She was the boss and a hostage until a minute ago, she needed a wand now until they got hers back. Besides, hello, she was pregnant. Higher priority for need of wand.
Nodding approval to Miles, as he was doing just as she had predicted, Hestia looked at Ernie in her best approximation of furious disbelief. "Yes, fine, fine, they haven't touched me. What do you mean, what they hell happened?" she demanded, as planned. It had to seem as though she thought they were here to rescue her, that she didn't have any idea where she was. "Death Eaters kidnapped me and replaced me with whoever you've got in custody!"
"We don't have anyone in custody!" Miles shouted, planting his shoulder against the door to stop any entry, clearly doing his duty as a good Auror despite his distress. "We didn't fucking know you'd been kidnapped!"
"Then how are you two here?!"
"You're in their fucking Cornwall hideout," Miles yelled, gesticulating wildly, "the one we've been planning to raid since the anonymous tip!"
