Mini-excerpt:  

 
 
Sadly not all ponies were as kind as spark had been. A lot of them shouted abuse, leaning out of windows rather then answer the door to him. Only when he unravelled the scroll showing the royal doctors seal did they listen to him. Many had little splinters much like Shining Sea. Sombra instructed them the way the doctor had told him. Remove the splinter, disinfect, cover with band aid, drink medicine. Rinse and repeat.
 
 
By the 20th house hed been to, he was starting to feel the effects of all the running and the rain. He couldnt stop shivering.
 
 
He looked like a drowned rat, but he didnt care. He just wanted this over with.
 
 
One or two he came across had larger splinters, and he had to tell their families to bring them to the palace…
 
 
Those that werent so sick were encouraged to go check on their neighbors and so on.
 
 
By the time he got to the last street, something was bugging him. Aside from the hostile reactions he was getting, he had a headache. Had he not been so exhausted he might have recognized it for the premonition it was.
