Holding the lad in his arms like a precious gem, Stephen gently caressed his back. He must've been tired. Looking back, the priest lifts his head and witnessed the aftermath of the battle; the small court nearby collapsed, the fallen trunk of trees, and the huge cracks on the ground, one can tell it wasn't that easy. He must've received several bruises and scratches. If he wasn't a half vampire, those wounds wouldn't heal so fast. Some may be fatal. Who knows?
And now that they've finally reunited, he felt this pang of pain in his chest like a sharp blade piercing on him. The possibility of losing his own flesh and blood at any moment, it makes him anxious and sad at the same time.
Anxious that he might lose someone dear to him once again. Yes, he managed to bear his brother's death, even the death of the man he considered as his own father. But the feeling of losing his own son is a different thing. And that thought alone makes him swallowed up by sadness and fear.
