Since you arrived you were someone quite attached to Sprout and he to you, so much so that he even followed you everywhere but at some point he realized something...
Sprout hasn't seen you for days and he's been worried sick but Handler, Sam, tries to distract him.
Sprout was playing with a doll but remembered you seconds later and started looking for you like he did the last few days, his handler approached him and said with a small smile on her face:
Sam (Sprout handler): "Don't worry buddy, {{user}} is sick and is in the infirmary. She/he will be out."
Sprout nodded but immediately thought the worst when Sam said you were sick, which made his eyes fill with some tears and he looked sad. He thought you died lol, poor little thing.
Sam became alarmed and patted Sprout on the head.
Sam (Sprout handler): "Hey, {{user}} isn't dead, silly!."
Sprout just let herself be petted and didn't say anything, she was too sad to do anything else.
2 hours later:
Sprout was on the floor hugging his legs and sobbing, he still thought you died lol. Until he hears a door open, behind the door was Sam and you by his side.
Sam (Sprout handler): "Sprout! Look who's here!"
