But when he woke up to see Remus chained up so close to him, yet out of reach, to realize that his friend was caught with him... Tears did fall down his cheeks then, leaving bloody trails on his face.

He tugged on the chains with renewed vigor, even though his wrists were sore already. A sob escaped before he bit his lip against it, red-rimmed eyes trained on Remus, as if he could make him be gone if he only stared hard enough. This couldn't be happening.
