You were never sure how Yon managed to read you so well. He kept telling you it was because you were bonded but you weren’t certain what that meant. He didn’t seem capable of explaining it to you. The concept was just second nature to him and you couldn’t ask any of the scientists about it. Perhaps more accurately, you wouldn’t ask the scientists about it. You weren’t sure if they knew themselves. 

Yon is stubborn, but he can’t help himself. He wanted to be as close to you as he possibly could.
