The spell broke with Pepper's words, Robin standing and shaking. 
There was no way to explain what had happened, no way without saying something utterly impossible.
He felt some shock and it was clear, despite the tears, that Pepper was in some as well.
But it was one thing at a time.
He glared at the boys who were stood not moving and ordered them to take Pepper to the forge.
"There's barrels there for burns," he said, knowing from years of experience what he was seeing. "Go there with him and put his hands in there. Do it now."
Robin's voice was cold and calm, which was unlike him. The boys did as they were told, forcing their blubbering leader with them.
"It's lavender," said Robin to no one imparticular, but since only Kes and Jube were left, they were the only ones to hear it. "Lavender is amazing for burns, which is why it's in the forge."
Kes seemed to lose what was left of her strength. Jube was safe. She knew that, so she felt the world fall away to darkess.
It was Jube's turn to hear Robin, the same careful, calm but serious tone he's used on the boys.
"Jube, I'm going to take Kestral home," he said, stepping forward to take her weight. "She's hurt and needs to be seen to. You are going to go home. You will [i]not[/i] tell anyone what happened, or come to see Kestral. You will wait at home whilst I take Kestral."
Kestral looked so small as Robin lifted her into his arms, her face dirty and her scarf, as well as her clothes, ruined.
"Go home, Jube," he repeated, before turning from him and walking away with Kestral in his arms. "If you do anything silly, Kestral will get upset and possibly hurt in the process. I know you don't want that."
