This takes place in episode three when Guin and Remus get locked the same prison cell, surrounding the time that they're shown in it. Slight artistic license taken.
Guin raked his head's fur with his hands, being careful not to pull his head off with his abnormal strength. He was in a horrible situation. He couldn't remember his name or any of his past, let alone why he was cursed to have the head of a leopard. He'd come upon the two defenseless children in the forest and felt a sort of pity for them; and trying to keep them alive and well took effort. The girl- Rinda, was it?- had grown on him. The boy had not. So of course, with the way his current luck was running, the boy was his cell mate.
"Hey Guin!" the boy exclaimed. "Look at this! When I move my hands like this, it looks like my thumb is floating!"
Guin grunted.
The prince continued. "And when I change them like this, it's like a butterfly! It's so pretty, isn't it?"
Guin grunted again.
"Hey, it kinda looks like I only have eight fingers now. Isn't it cool?"
Guin let out a low growl.
"Oh, are you hungry? I'm hungry. Maybe they'll feed us soon. I know Big Sis always made sure I got a lot of food. Too bad she's not here, huh."
Guin silently agreed.
The slat on the door opened up, and two trays of food came in shortly afterward. The boy couldn't let this pass without comment either. "It's food! Let's eat it."
Guin felt a strong urge to ignore him. But it passed as quickly, as his stomach was currently controlling his thoughts. Maybe if the fool's mouth was full, he wouldn't be able to talk as much. Maybe if he paid attention when his sister taught him manners, he might not talk at all while he was eating.
"Yeah."
It was worth a try.
