Sebastian would like to think he was a flexible man. Easy-going, lax, open-minded. He made sure that even on duty, he had high toleration.
What he absolutely would not stand, is one's own foolishness. He knew it was not Attila's fault. Human emotions come at random. They're unpredictable. Something science could never touch. It was just bad luck that love started to play on his heartstrings at this very moment.
Sebastian wasn't angry at that. No, not at all. But he did wish Attila had the brain and common sense not to look longingly at Hun when they were 3 fucking feet away from the rabid beast.
"What happened? You don't usually mess up that bad," he heard Hun say. Emotionless cover as usual, but Sebastian could hear something different in his tone.
"It's nothing."
Even with his back turned to them, Sebastian could very much guess what'll happen next. They were smart. It wouldn't take them long to realise what's going on between them.
He was sure, by the time he reached the cave door, they would confess their undying love for each other.
He'd rather not be around when that happens.
