A gem for a beauty

It was a tough scale down the wall. It was tricky to control not only Jack's own body weight but that of the kids holding on to him. There were times when he wanted to jump down, but was afraid the kids would be hurt in the process. 

While going down the wall, the kids constantly nagged at him. 

"Come on, you're so slow." one of them said. 

"We won't even have much time to explore the city at this rate." Another complained. 

"Don't be too hard on him, he's trying his best." Rachel said.

Below, Jack could see that the two teenagers had already made more progress than him and we're scaling it with ease. When taking a closer look, he noticed that their hands were covered in fur. They had been digging their claws into the stone, making it easier to find a hold and grip. 

Trying to do the same, Jack closed his eyes. 

"Come on, you can do it!" Jack said. 

"Hey, why did we stop. Is he tired already." the kid complained.
