A no-maj. Of all the little boys in the world, the Professors and both Headmistresses decided to break the statute of secrecy and bring them one that was not supposed to know this place existed in the first place. If he was not so focused on getting them out of there and on how much worse this just became, Aiden may have laughed from the sheer absurdity of it all.

Trying to remain focused, Aiden shook his head and instead offered the boy a smile while he kept walking. "Don't worry about it, I've got you now and we are gonna make it out of here."

He reminded him of his younger brother Samwell and it made him all the more determined to save him. Being a no-maj there was little chance some accidental magic would kick in to save the day. This would be left up to him.

"Don't worry about it. No matter what pops out, I will make sure we get out of here safe and sound. I can tell you a little secret, I am actually a superhero in disguise." Had to establish some competence and credibility, no need to have the boy ask how he planned to save him. "So how about we think of some happy thoughts and when we get out of here, I will personally get you a large bar of chocolate. You like chocolate, right?"

He heard the owl. It was hard to ignore the ominous sound and the sinking feeling that tried to creep up on him. For the sake of the little guy, he would have to remain calm. "What is the funnest thing you have ever done?" He would just distract him from the terror and hope to get them out soon.
