Noah was, honesty, drained at this point emotionally and physically. The Room was beginning to take a toll on him as much as he'd like to hide it..... He was doing a poor job hiding it and putting on a brave face. At this point, doom & gloom was his norm. So he just walked into the room, nodded at the Professor, before stopping when he saw the question.

"uh, Hi Professor.... Intriguing question..." he commented. It was all he could offer at this point before he headed to find a seat in the classroom.

Why do we feel itchy? he repeated in his mind. Easy. Allergies or Dust Mites... he thought, before taking a sit somewhere in the middle of the classroom. He really didn't feel like talking today.... He'd rather be in his own world.... At least in his own world, he couldn't get himself or anyone in trouble.
