(ooc: wait..robert apparated out in my last post. he's already at diagon alley. i'll adjust in my post)
Robert had summoned every available auror and then had gone to be with the others in battling the fiendfyre. The corpses that filled the once pleasant street was overwhelming. Robert had his suspicions, but he didn't know much of anything for certain. Sparks was fully engulfed and, he was sure, would be a total loss. He had dispatched whoever he could find to go look for Khaat. So far, her body had not been found. No one had found any remainders of a body in Sparks, so he was starting to think she'd been taken. The aurors were already swiftly coming to the same conclusion. And there were rumors that the Death Eaters had been in the area at the time of the fire but they weren't here now.
When Steven came up to him, Robert just entirely missed that Steven said he wanted to talk. It wasnt' intentional. Robert was preoccupied. "Steven," Robert said. "Good. Khaat was in Sparks, but she's not there now--not that we've found. Start combing through the bodies. So far, the aurors haven't found her among them. If she's not there, then our buest guess is that she's been taken hostage by the Death Eaters. Steven--this is one time when I honestly don't want you to find her." The last thing Robert wanted was for Steven to find his daughter's corpse among all the others that had been victims of the killing curse and who were lying dead in the street. If she wasn't there, then there was a possibility that she was still alive.
(I'll skip time in my next post so he, or whoever you choose, can find her.)
