Harry pressed at the black spot on his arm. "I don't feel anything different with mine. It's more just concern than anything. I woke up with it this morning after nightmares of being tortured. Even if it doesn't hurt that's enough to seem strange." Harry hadn't actually asked if anyone else had one. He should have asked Hermione earlier but he'd been focused on Zurlo, on nightmares, and later on Pandora.
"I don't know, but that might be something to look into. It may not be a much to worry about, but-" But he couldn't see it as anything good. Harry very nearly moved to rub at his eyes again, between having had that nightmare and his hand going to his head being ingrained in him by now as a response to worry. But he stayed his had and just rolled back down his sleeve. "It might be nothing of concern," he added, though he wasn't really sure.
