Yeah, he was Joshua Carter.

And after quite a short time he had uttered his name, Josh could realise the slight change of expression on the dude's face. It looked like he had recognised his name which made Josh curious to know where did this fellow MLE worker knew his name from or where they had met before. It could very well be Hogwarts as he had stated before. He was yet to find out.

Then the man revealed his name. As soon as he heard it together with the last name, Josh felt like something 'clicked' in his brain. That name definitely sound very familiar. Had to be Hogwarts, he was sure of it and...

...and then he thought he remembered. The Auror tilted his head to the side a tiny bit and a single word escaped his mouth before he could think of it or anything else. This was his first reaction to remembering him. "Stutters?"

Except that he was not stuttering anymore.
