Throwing a few bits onto the table and Kid onto Brawny's back, and despite he condition, Calla galloped out of the diner, which was luckily not too far from her old home. Last she had heard, Amina had returned to Ponyville and was planning to stay for a while, and she knew exactly where.
Banging on the door to the cottage, she waited until somepony answered.
"Oh, hi, Calla," Cloud said, smiling brightly at her friend. "I haven't seen you in-"
"There's no time, Cloud, and I apologize," Calla said quickly, "but my son is terribly ill. Is Amina home?"
Cloud nodded, ushering the ponies in.
"She'll be down in a moment. She's writing a letter back to her Princess, but I'll go call for her."
Gesturing to Calla's old bedroom, she ducked out and went off to find Amina.
Calla took Brawny and Kid into her old bedroom, laying the sick foal down on the bed and waiting impatiently for her friend.
"Faust, I hope she can help."
