When Klein saw Mr. G in green overalls appear at Hogwarts Castle, he stood there dumbfounded for quite some time.
What was going on?
Why was his unlucky great-uncle here at the school?!
Wait.
Did this mean Dumbledore already knew about it?
A thousand thoughts flashed through Klein's mind, leaving him looking dazed.
But Gellert was in a very good mood. He smiled and greeted him.
"Hi, Little Klein. Good morning!"
"Uh, good morning."
Klein nodded woodenly.
"Lovely weather, isn't it?"
As if this were the most ordinary small talk, Gellert looked every bit like a kindly old neighbor.
"Yeah."

"Mr. G, what are you doing here?"
"Oh, this is where I work."
Gellert flashed a row of somewhat crooked teeth.
"I've officially been hired by Hogwarts as a cleaner."

Klein looked puzzled.

"All right, I'd better get back to work. See you."
Seeing Klein first thing in the morning had put Gellert in a good mood. He picked up his bucket and ambled away, leaving Klein standing there, bewildered.

Klein thought it over for a while, then decided he would ask Dumbledore about it later.

As soon as he stepped inside, he heard the students greeting him.
"Good morning, Professor Grindelwald."
Their perfectly synchronized greeting was clearly rehearsed. Klein was taken aback, then broke into a bright smile.
"Good morning, students."
