Adrian hadn't had much of a chance to see if the others were wearing them either. The badges were small enough to not be seen unless you were close enough, or at least not in the middle of fighting what was wearing it. "That's a safe assumption and can be easily tested," Adrian responded. One could detect if an object was a portkey if one actually knew to look rather than accidentally touch it and find out the hard way. It was part of the reason he wasn't touching it with his hands. He'd no idea what it might do. It clearly wasn't what was causing these things to be.
Adrian gave it another look, taking in a few more details before setting it down. Then he bound the creature even further, restricting its movement to completely futile struggles. It could hardly move more than an inch in either direction. "Whenever you're ready then." He was intrigued to see what was going on inside its head, if anything.
