Adrian didn't bother to point out he'd already expressed concern as to how these things had gotten into the ministry. Answers could come later. Action needed to be taken now. But that didn't mean Adrian couldn't get a good look at them while he tried to round them up.
They were all - at least what he could see because he'd only seen now and now a third coming around the corner - wearing the same sort of pyjamas, ones that looked familiar. It hit him suddenly as he bound the newest one as it headed for him, that they were wearing what prisoners in Azkaban wore.
Behind him, Chambers said they had a pulse and that confirmed Adrian's thought about the clothing. What the hell was going on here? What were this things? They clearly weren't conventionally alive, but if they had a pulse... "Try to see if we can keep at least one to have a look at. Something's really not right here."
If there was a prison break from Azkaban...Adrian felt cold at the though of seeing his uncle like this. Were these just regular prisoners? "They're not just imperiused," he replied. "Imperius doesn't make you look like an inferius. There's more to it than just a controlled breakout," he added.
