"Kellen! Are you alright?" Gwen's voice was shaking as he coughed. He sucked air into his lungs again before looking up. Gunther stood behind the panicked Gwen, and gone was his cocky, excited expression. Instead, his face was stern as he looked Kellen over. 

"I'm sorry Kellen." He apologised, his tone somber and Kellen coughed again. He rubbed his throat. It felt sore, but he knew it was only temporary. It should be fine tomorrow, maybe even later tonight. 

"I-It's alright. I almost called a stop to it at the S Class level." His voice was a little scratchy, but nothing painful. Gwen's eyes were saucers. 

"You're a Guide! You have a weaker body than us! You should have!" She was very upset, and Kellen grinned at her, reaching out to touch her face. 

"Come on Gwen, this isn't the worst I've had before. Gunther stopped it in time." Gunther and Gwen didn't seem appeased.
