“Mmh.” Alhaitham hummed, moving the little whiteboard he had back towards you. You had been writing math problems out for him to solve. Despite regressing to about two or three years old, Alhaitham absolutely loved doing complex math problems.

You wrote out another problem for him, a long multiplication problem that you hoped would keep him busy for another few minutes. The white board was moved back in front of Alhaitham as he stared at it for a moment. You could almost see the gears turning in his head as he thought over the problem.

Alhaitham took the marker and began working away, all of his focus on the numbers in front of him. A Hilichurl could run through the house like a mad man and Alhaitham probably would have no idea.
