"Damn it, Remus!" With a sweep of her wand, Tonks knocked an empty glass decanter from the bench. "I'm not my cousin, I never will be!"
There was a long silence and then a chink and a tinkle as Remus, bending down, retrieved the shards of glass. Standing straight again, he replied quietly. "I never said you were." He moved to lay the pieces down on the bench, next to a ceramic vase that had been broken earlier, but she stepped in his way.
"No, but you act like I am!" Tears fell freely down her face. "I see the way you look at me. When you think I'm not watching." Tonks' blue eyes flashed. "It's the same way you look when you're reading over those bloody letters Sirius wrote!"
"I don't know what you mean…" Remus fumbled awkwardly with the broken glass in his hands.
"Sirius is dead, Remus."
"I know that."
"Do you?" Tonks took a small step closer to him, looking up into his hazel eyes. "Do you really know that?" Remus flinched as if he had been slapped, and twisted round towards the door. "Don't turn away from me!" She grabbed his hand, and led him back towards where they had been standing. "I can't go on like this. I can't go on pretending," she sobbed. "Pretending that I don't know what you're thinking when you see me, when you touch me, when you hold me."
Remus looked pained, and he didn't say anything for a moment. Finally, "I care about you, Tonks. I care a lot. You're my only- You're my Nymph, my Tonks."
"But I'm not your Sirius. And you cared about him, too."
"Yes, I did." He let his gaze drop despondently to the floor.
"Damn it, Remus!" She tightened her clutch on his hand, not caring about the sounds of crunching glass between his fingers. She waited for him to cry out in pain, but he didn't, it never happened.
"I – I love you."
"Look at me." Remus raised his eyes to meet hers. "Look at me, and tell me honestly. Truthfully. Tell me that there is never a moment where you wish that Sirius were here, instead of me, even if it meant that I was dead. If you can't do that…" She released her grip on his hand but he didn't move.
"I- that's- I…" he stumbled.
"Just go." Tonks shut her eyes, and turned away, making no effort to stem the flow of tears down her cheeks. "Just- just go."
"But I-"
"Leave. Remus, just go. For now. Just go."
After a long pause in which neither of them spoke, Remus nodded. He emptied his hand onto the bench of the glass pieces, now stained with his blood, and turned towards the door. He hesitated, turned back, and kissed Tonks sadly on the cheek. She didn't respond, and Remus walked out, closing the door quietly on the fragile reality that they had tried to create in the aftermath of tragedy.
